Description

Screen-off display method and electronic device

[0001] The present application claims priority from the Chinese patent application No. 202411050772.6 filed on July 31, 2024, and entitled "Screen-off display method and electronic device", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the technical field of terminals, and in particular to a screen-off display method and an electronic device. BACKGROUND

[0003] Always on display (AOD) can be used to display time, date, pictures, and other AOD content on the display screen after the electronic device is turned off. The current AOD content has less interaction with the user, and the user experience is not good. SUMMARY

[0004] The present application provides a screen-off display method and an electronic device. In the screen-off display state, the electronic device can detect an event for moving AOD content, and move the AOD content on any display area of the screen according to the event for moving the AOD content. Moreover, when one display area displays AOD content, other display areas that do not display AOD content can be in a powered-off state. The method can improve the interactivity of AOD content while reducing the power consumption of the electronic device in the screen-off display state.

[0005] In a first aspect, the present application provides a screen-off display method. The method is applied to a first device, and the first device includes a first display area and a second display area. The first device detects a screen-off event; according to the screen-off event, the first device displays AOD content in the first display area; when the first display area displays AOD content, the second display area is in a powered-off state; the first device detects a first event; according to the first event, the first device powers on the second display area and displays AOD content in the second display area; when the second display area displays AOD content, the first display area is in a powered-off state.

[0006] The first event includes: a human eye gazes at the second display area, or a user performs a touch operation on the second display area.

[0007] It can be seen that in the screen-off display state, the first device can move the AOD content between the plurality of display regions of the display screen according to the event for moving the AOD content, such as the eye gaze area or the touch operation of the user acting on the display region. In this way, the interactivity of the AOD content can be improved. Moreover, the first device can power on the display region displaying the AOD content and power off the display region without displaying the AOD content. This not only can reduce the power consumption of the first device in the screen-off display state, realize the all-day display of the AOD content on the display screen, but also can reduce the damage of the display screen in the powered-on state for a long time. The above method can improve the user experience of the user using the AOD.

[0008] In combination with the first aspect, in some embodiments, before displaying the AOD content in the second display region, the first device plays a first animation corresponding to moving the AOD content from the first display region to the second display region.

[0009] For example, the first animation can include a first image sequence. The images in the first image sequence can be arranged in order of display. Among them, the image with earlier order in the first image sequence is displayed more in the first display region. The image with later order in the first image sequence is displayed more in the second display region. In this way, the display position of the image in the first image sequence can gradually move from the first display region to the second display region according to the preset moving path. The image content of the plurality of images contained in the first image sequence can be different (for example, the first image sequence contains a plurality of images of butterflies flying, and the state of the butterflies flying in each image is different). In this way, the animation effect of the object in the AOD content moving from the first display region to the second display region can be presented. Alternatively, the image content of the plurality of images contained in the first image sequence can be the same. That is, the AOD content can be a static image, and the first device can translate the static image from the first display region to the second display region.

[0010] The scenario in which the first device plays the first animation can refer to the scenario shown in FIGS. 4A-4E, or the scenario shown in FIGS. 5A-5C, or the scenario shown in FIGS. 6A-6E, or the scenario shown in FIGS. 7A-7C, or the scenario shown in FIGS. 8A-8E.

[0011] It can be seen that the first device can play an animation of moving the AOD content in the process of moving the AOD content. This animation can provide stronger interactivity for the user, and the user can better perceive the process of the AOD content moving with the change of the eye gaze direction or the change of the touch operation acting area. In this way, the user experience of the user using the AOD on the first device can be improved.

[0012] In some embodiments, the first device comprises a third display area, the third display area being a display area through which the AOD content moves from the first display area to the second display area; the first device powers on the second display area and the third display area according to the first event; the first device moves the AOD content from the first display area to the third display area, and then moves the AOD content from the third display area to the second display area; and the first device powers off the first display area and the third display area.

[0013] Optionally, when the AOD content moves to a first position of the first display area, the first device powers on the third display area, and a distance between a boundary of the third display area and the first position is less than a first threshold; when the AOD content moves to a second position of the third display area, the first device powers on the second display area, and a distance between a boundary of the third display area and the second position is less than a second threshold; when the AOD content moves out of the first display area completely, the first device powers off the first display area; and when the AOD content moves out of the third display area completely, the first device powers off the third display area.

[0014] It can be seen that, in the process that the AOD content moves from the first display area to the second display area through the third display area, the second display area and the third display area can be powered on according to the moving position of the AOD content. The first device can power on the display areas that need to display the AOD content according to the moving situation of the AOD content. In this way, the first display area, the second display area and the third display area can not be in the powered-on state all the time in the process that the AOD content moves from the first display area to the second display area, thereby reducing the power consumption of the first device.

[0015] In some embodiments, the first device plays a first audio in the process that the AOD content moves from the first display area to the second display area.

[0016] The above embodiments can provide the user with the transition sound effect of AOD movement, and improve the user experience of using the AOD.

[0017] In some embodiments, the first device comprises a first speaker and a second speaker, the first speaker being located on the left side of the first device, and the second speaker being located on the right side of the first device; if the first display area is on the left side of the second display area, the first device gradually reduces the loudness of the first audio played by the first speaker, and gradually increases the loudness of the first audio played by the second speaker; and if the first display area is on the right side of the second display area, the first device gradually reduces the loudness of the first audio played by the second speaker, and gradually increases the loudness of the first audio played by the first speaker.

[0018] The first speaker can be the left speaker of the first device. The second speaker can be the right speaker of the first device.

[0019] In some embodiments, the first device includes a first screen, a second screen, and a third screen arranged from left to right. The first and second screens are foldable around a first folding edge, and the second and third screens are foldable around a second folding screen. A first speaker may be located at the position of the first screen. A second speaker may be located at the position of the third screen.

[0020] If the first display area is the display area on the first screen, and the second display area is the display area on the third screen, during the process of AOD content moving from the first display area to the second display area, the first device can first use the first speaker to play the first audio. The first device can gradually decrease the loudness of the first audio played by the first speaker. When the AOD content moves to the corresponding display area on the second screen, the first device can use both the first and second speakers to play the first audio. Specifically, the first device can continuously decrease the loudness of the first audio played by the first speaker and gradually increase the loudness of the first audio played by the second speaker. When the AOD content moves to the second display area, the first device can stop using the first speaker to play the first audio and use the second speaker to play the first audio until the AOD content stops moving.

[0021] As can be seen, the first device can adjust the speaker playing the first audio based on the direction of movement of the AOD content. This allows the transition sound effects to change with the movement of the AOD content, improving the user experience when using AOD.

[0022] In conjunction with the first aspect, in some embodiments, the first device further includes a fourth display area. The first device detects a second event, the second event including: a person's eye looking at the fourth display area, or a user performing a touch operation on the fourth display area; according to the second event, the first device powers on the fourth display area and displays AOD content in the fourth display area; wherein, when the fourth display area displays AOD content, both the first display area and the second display area are in a powered-off state.

[0023] The fourth display area can be any area on the display screen of the first device. The fourth display area is at least partially different from the first display area. The fourth display area is at least partially different from the second display area.

[0024] As can be seen, users can move AOD content from the first display area to the second display area, and then from the second display area to the fourth display area, by changing the direction of their gaze or by performing touch operations on the display area. This can improve the interactivity of AOD content.

[0025] With reference to the first aspect, in some embodiments, the first device comprises a first screen, a second screen and a third screen arranged from left to right, the first screen and the second screen are foldable about a first folding edge, and the second screen and the third screen are foldable about a second folding edge; if the folding screen of the first device is in a fully unfolded state, the first display area and the second display area are any areas on the first screen, the second screen and the third screen, wherein the fully unfolded state is a state in which the first screen and the second screen are fully unfolded, and the second screen and the third screen are fully unfolded; if the folding screen of the first device is in a half-folded state 1, the first display area and the second display area are any areas on the second screen and the third screen, wherein the half-folded state 1 is a state in which the first screen and the second screen are fully folded, and the second screen and the third screen are fully unfolded; if the folding screen of the first device is in a half-folded state 2 or a fully folded state, the first display area and the second display area are any areas on the first screen, wherein the half-folded state 2 is a state in which the first screen and the second screen are fully unfolded, and the second screen and the third screen are fully folded, and the fully folded state is a state in which the first screen and the second screen are fully folded, and the second screen and the third screen are fully folded.

[0026] The first screen can refer to the A screen in the embodiments of the present application. The second screen can refer to the B screen in the embodiments of the present application. The third screen can refer to the C screen in the embodiments of the present application.

[0027] It can be seen that in different folding states, the screen used by the first device for display can be different. That is, in different folding states, the range of movement of the AOD content can be different.

[0028] With reference to the first aspect, in some embodiments, the first display area and the second display area are display areas on different display screens of the first screen, the second screen and the third screen; or the first display area and the second display area are different display areas on one display screen of the first screen, the second screen and the third screen.

[0029] It can be seen that the AOD content can move between different display screens, or move between different areas of one display screen. That is, the first device can move between any areas of the folding screen according to the event used to move the AOD content. In this way, the accuracy of the position movement of the AOD content can be improved, and the interactivity between the user and the AOD content can be better improved.

[0030] In combination with the first aspect, in some embodiments, the first device further comprises a fifth display area, the folding screen of the first device is in a first folding state, the first folding state is one of a fully unfolded state, a half-folded state 1, a half-folded state 2, and a fully folded state; when the folding state of the folding screen changes to a second folding state, the first device displays AOD content on the fifth display area, the second folding state is one of the fully unfolded state, the half-folded state 1, the half-folded state 2, and the fully folded state, and the second folding state is different from the first folding state; when the fifth display area displays the AOD content, the display area outside the fifth display area is in a powered-off state.

[0031] In the second folding state, the fifth display area is a display area in the first screen, the second screen, and the third screen. For example, the fifth display area can be the entire area on any one of the first screen, the second screen, and the third screen, or the fifth display area can be a partial area on any one of the first screen, the second screen, and the third screen, or the fifth display area can be the entire area of the first screen and the second screen, or the fifth display area can be composed of a partial area of the first screen and a partial area of the second screen, or the fifth display area can be the entire area of the second screen and the third screen, or the fifth display area can be composed of a partial area of the second screen and a partial area of the third screen.

[0032] In the second folding state, the fifth display area is a display area in the first screen, the second screen, and the third screen. For example, the fifth display area can be the entire area on any one of the first screen, the second screen, and the third screen, or the fifth display area can be a partial area on any one of the first screen, the second screen, and the third screen, or the fifth display area can be composed of a partial area of the first screen and a partial area of the second screen, or the fifth display area can be the entire area of the second screen and the third screen, or the fifth display area can be composed of a partial area of the second screen and a partial area of the third screen.

[0033] In the second folding state, the fifth display area is a display area in the first screen, the second screen, and the third screen. For example, the fifth display area can be the entire area on any one of the first screen, the second screen, and the third screen, or the fifth display area can be a partial area on any one of the first screen, the second screen, and the third screen, or the fifth display area can be composed of a partial area of the first screen and a partial area of the second screen, or the fifth display area can be the entire area of the second screen and the third screen, or the fifth display area can be composed of a partial area of the second screen and a partial area of the third screen.

[0034] As can be seen, the first device can move the AOD content as the folding state of the folding screen changes. The user can change the display position of the AOD by changing the folding state of the folding screen. This can improve the interactivity of the AOD content.

[0035] With reference to the first aspect, in some embodiments, during the change of the folding state of the folding screen from the first folding state to the second folding state, the first screen, the second screen, and the third screen are all in a powered-off state, and when the folding state of the folding screen changes to the second folding state, the first device powers on the fifth display area. For details, refer to the scenarios shown in FIGS. 10A to 10D of this application.

[0036] It can be seen that when the folding state of the folding screen changes from the first folding state to the second folding state, the first device can power off all the screens. The first device can power on the display area (i.e., the fifth display area) that needs to display the AOD content after the folding state of the folding screen changes to the second folding state. In this way, the power consumption of the first device can be reduced.

[0037] With reference to the first aspect, in some embodiments, when the folding screen is in the first folding state, the AOD content is located in the second display area, and during the change of the folding state of the folding screen from the first folding state to the second folding state, the first device plays a second animation that moves the AOD content from the second display area to the fifth display area. For details, refer to the scenarios shown in FIGS. 11A to 11C of this application.

[0038] For example, the second animation can include a second image sequence. The images in the second image sequence can be arranged in order of display. Among them, the earlier the image is arranged in the second image sequence, the more part of the image is displayed on the second display area. The later the image is arranged in the second image sequence, the more part of the image is displayed on the fifth display area. In this way, the display position of the image in the second image sequence can gradually move from the second display area to the fifth display area according to a preset moving path. The second image sequence can refer to the first image sequence described above.

[0039] It can be seen that the display position of the AOD content can change with the change of the folding state. Moreover, during the change of the folding state, the first device can display an animation of the movement of the AOD content in the corresponding display area. When the user changes the folding state of the folding screen, the user can intuitively see the movement process of the AOD content. In this way, the interactivity of the AOD content can be improved. In addition, in the above scenario of changing the display position of the AOD content according to the change of the folding state, the first device can power on the display area that needs to display the AOD content and power off the display area that does not need to display the AOD content. In this way, the power consumption of the first device can be reduced.

[0040] In some embodiments of the first aspect, the first device further includes a sixth display area, the AOD content is located in the second display area, the first device detects a first sliding operation, a start point of the first sliding operation is located in the second display area, and an end point of the first sliding operation is located in the sixth display area; according to the first sliding operation, the first device powers on the sixth display area and moves the AOD content to the sixth display area according to a sliding track of the first sliding operation; and when the sixth display area displays the AOD content, display areas outside the sixth display area are in a powered-off state.

[0041] It can be seen that the user can perform a sliding operation on the display screen to move the AOD content following the sliding of the finger on the display screen. The above embodiments can improve the user experience of the user using the AOD.

[0042] In some embodiments of the first aspect, the first device is connected with a second device, a fourth screen of the second device is an extended display screen of the first device, the AOD content is located in the second display area, the fourth screen is in a powered-off state, the first device detects a third event, the third event includes that a human eye gazes at the fourth screen or a user performs a touch operation on the fourth screen, and according to the third event, the first device instructs the second device to power on the fourth screen and display the AOD content on the fourth screen; and when the fourth screen displays the AOD content, the first display area and the second display area are in a powered-off state.

[0043] Optionally, the first device and the second device can play an animation corresponding to the movement of the AOD content from the second display area to the fourth screen and play corresponding audio to provide a transition sound effect of the movement of the AOD content to the user.

[0044] It can be seen that in the case where the first device is configured with an extended display screen, the first device can move the AOD content on any area of the display screen of the first device and the extended display screen, thereby improving the interactivity of the AOD content.

[0045] In the second aspect, the present application provides an electronic device. The electronic device can include a memory and a processor. The memory can be used to store a computer program. The processor can be used to call the computer program to execute any possible implementation method in the first aspect.

[0046] In the third aspect, the present application provides a computer readable storage medium storing instructions, which can be executed by a processor to implement any possible implementation method in the first aspect.

[0047] In the fourth aspect, the present application provides a computer program product, which can include computer instructions, when the computer instructions are executed on a processor, can implement any possible implementation method in the first aspect.

[0048] In a fifth aspect, the present application provides a chip, which is applied to an electronic device, and the chip comprises one or more processors configured to invoke computer instructions to cause the electronic device to perform any possible implementation method of the first aspect.

[0071] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application. In the description of the embodiments of the present application, the terms used in the following embodiments are only for the purpose of describing the specific embodiments and are not intended to be limiting on the present application. As used in the specification and the appended claims of the present application, the singular forms “a,” “an,” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that “at least one” and “one or more” as used in the following embodiments refer to one or two or more (including two). The term “and / or” is used to describe the association relationship of the associated objects, which means that there can be three relationships; for example, A and / or B can represent the following three cases: A exists alone, A and B exist together, and B exists alone, where A and B can be singular or plural. The character “ / ” generally represents an “or” relationship between the associated objects.

[0072] Reference in the specification to "one embodiment" or "some embodiments" means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment. The appearances of the phrase "in one embodiment" or "in some embodiments" in various places in the specification are not necessarily all referring to the same embodiment, although it can. The terms "including," "comprising," "having" and variations thereof are meant to encompass the items listed thereafter and equivalents thereof as well as additional items. The terms "connected" and "coupled" are not restricted to direct connections or couplings but include indirect connections or couplings through another component or components. The terms "first," "second," and "third" are used to describe various elements, but can not be understood as indicating or implying relative importance or a number of indications of the elements.

[0073] In the present application, the word "exemplary" or "for example" is used to mean "an example of" or "an example, only. Any implementation described herein as "exemplary" or "for example" is not necessarily to be construed as preferred or advantageous over other implementations. The described exemplary implementations are examples, and the application can include further implementations more numerous, less numerous, different, or even the same exemplary implementations without departing from the scope of the application. Additionally, the described exemplary implementations are not necessarily to be construed as having any relationship with the prior art. The word "for example" is used only to reference one or more examples, any implementation, or the like, not to imply a preference or inherent superiority of the example over other implementations.

[0074] In some embodiments, after the electronic device is turned off, the AOD content can be displayed in a partial area of the display screen, and the area of the display screen where the AOD content is not displayed can be powered off. The AOD content displayed in the partial area can be static, that is, unable to interact with the user. Alternatively, the AOD content displayed in the partial area can be dynamic. However, in order to reduce the power consumption of the electronic device in the turned-off display state, only a part of the elements in the AOD content can dynamically change in the partial area according to the user input. The user interaction with the AOD content is limited to a limited display area on the display screen, and can only interact with individual elements in the AOD content, which is poor in interactivity. In addition, on a foldable screen, especially a multi-fold screen, the above-mentioned partial display of the AOD content displays the AOD content in a small area of the foldable screen, which is poor in overall layout.

[0075] In some embodiments, after the electronic device is turned off, the AOD content can be displayed in a partial area of the display screen, and the area of the display screen where the AOD content is not displayed can be powered off. The AOD content displayed in the partial area can be static, that is, unable to interact with the user. Alternatively, the AOD content displayed in the partial area can be dynamic. However, in order to reduce the power consumption of the electronic device in the turned-off display state, only a part of the elements in the AOD content can dynamically change in the partial area according to the user input. The user interaction with the AOD content is limited to a limited display area on the display screen, and can only interact with individual elements in the AOD content, which is poor in interactivity. In addition, on a foldable screen, especially a multi-fold screen, the above-mentioned partial display of the AOD content displays the AOD content in a small area of the foldable screen, which is poor in overall layout.

[0076] The present application provides a screen-off display method. After receiving a screen-off operation, the electronic device can display AOD content on display area 1 and power off display areas in the powered-on state except display area 1. In the screen-off display state, the electronic device can detect the gaze direction of the human eye. When it is determined that the human eye gazes at display area 2 according to the gaze direction of the human eye, the electronic device can power on display area 2, move the AOD content from display area 1 to display area 2, and power off display areas in the powered-on state except display area 2. Alternatively, in the screen-off display state, the electronic device can receive a click operation on the display area. When receiving a click operation on display area 3, the electronic device can power on display area 3, move the AOD content to display area 3, and power off other display areas in the powered-on state except display area 3. The above-mentioned display area 1, display area 2, and display area 3 can be display areas at any position on the display screen of the electronic device.

[0077] As can be seen from the above method, in the screen-off display state, the electronic device can move the AOD content between multiple display areas of the display screen according to the change of the gaze direction of the human eye or the change of the touch area. This can improve the interactivity of the AOD content. Moreover, the electronic device can power on the display area displaying the AOD content and power off the display area without displaying the AOD content. This not only can reduce the power consumption of the electronic device in the screen-off display state, realize the all-day display of the AOD content on the display screen, but also can reduce the damage of the display screen caused by being in the powered-on state for a long time. The above-mentioned method can improve the user experience of using AOD.

[0078] In some embodiments, the above-mentioned screen-off display method can be applied to an electronic device with multiple display screens. The electronic device with multiple display screens can include a folding screen device. The folding screen device can be an electronic device with a folding screen. The folding screen can be folded into multiple display screens. For example, a two-fold screen can be folded into two display screens. A three-fold screen can be folded into three display screens. The above-mentioned display area 1 to display area 3 can be display areas at any position on the folding screen. Exemplarily, the three display screens formed by folding the three-fold screen can be A screen, B screen, and C screen, respectively. The above-mentioned display area 1 can be a display area corresponding to the A screen. The above-mentioned display area 2 can be a display area corresponding to the B screen. The above-mentioned display area 3 can be a display area corresponding to the C screen. The electronic device can determine the display screen for display according to the folding state of the folding screen, and then display the AOD content in partitions on the display screen for display.

[0079] The folding screen device will be introduced below taking a three-fold screen as an example.

[0080] FIGS. 1A-1E illustrate some schematic diagrams of an electronic device 100 with a tri-fold screen.

[0081] As shown in FIG. 1A, the folding screen of the electronic device 100 can include an A screen, a B screen, and a C screen. Among them, the A screen and the B screen can be distributed on both sides of the folding edge 1 and can rotate around the folding edge 1. The B screen and the C screen can be distributed on both sides of the folding edge 2 and can rotate around the folding edge 2.

[0082] FIG. 1A shows a fully unfolded state of the folding screen. In the fully unfolded state, the angle between the A screen and the B screen is 180° or approximately 180°, and the angle between the B screen and the C screen is 180° or approximately 180°. The A screen, the B screen, and the C screen can be unfolded into a plane. In the fully unfolded state, the electronic device 100 can display the A screen, the B screen, and the C screen as a whole screen.

[0083] In some embodiments, a front camera can be disposed on the A screen.

[0084] In some embodiments, in the fully unfolded state, the A screen can rotate around the folding edge 1 in the direction 11a shown in FIG. 1A, and the C screen can rotate around the folding edge 2 in the direction 11b shown in FIG. 1A. For example, in the fully unfolded state, the angle between the B screen and the C screen remains unchanged, the A screen rotates around the folding edge 1 in the direction 11a, and the folding screen can form a semi-folded state 1 shown in FIG. 1B.

[0085] As shown in FIG. 1B, the folding screen is in the semi-folded state 1. In the semi-folded state 1, the angle between the A screen and the B screen is 0° or approximately 0°, and the angle between the B screen and the C screen is 180° or approximately 180°. The A screen and the B screen face away from each other. The B screen and the C screen are unfolded into a plane. In the semi-folded state 1, the electronic device 100 can display the B screen and the C screen as a whole screen.

[0086] In some embodiments, a front camera can also be disposed on the B screen and / or the C screen.

[0087] In some embodiments, in the semi-folded state 1, the B screen can rotate around the folding edge 2 in the direction 12a shown in FIG. 1B together with the A screen, and the C screen can rotate around the folding edge 2 in the direction 12b shown in FIG. 1B. For example, in the semi-folded state 1, the angle between the A screen and the B screen remains unchanged, the B screen rotates around the folding edge 2 in the direction 12a, and / or the C screen rotates around the folding edge 2 in the direction 12b, and the folding screen can form a fully folded state shown in FIG. 1D.

[0088] As shown in FIG. 1C, the folding screen is in a half-folded state 2. In the fully unfolded state shown in FIG. 1A, the angle between the A screen and the B screen remains unchanged, and the C screen rotates around the folding edge 2 according to the direction 11b, so that the folding screen can form the half-folded state 2. In the half-folded state 2, the angle between the A screen and the B screen is 180° or approximately 180°, and the angle between the B screen and the C screen is 0° or approximately 0°. The B screen and the C screen are opposite (i.e., in a face-to-face state). In the half-folded state 2, since the B screen and the C screen block each other, the electronic device 100 can use the A screen for display.

[0089] In some embodiments, the back of the C screen is provided with a rear camera. In the half-folded state 2, the back of the C screen and the A screen can face the user at the same time. The electronic device 100 can use the front camera and / or the rear camera to capture images.

[0090] In some embodiments, in the half-folded state 2, the A screen can rotate around the folding edge 1 according to the direction 13a shown in FIG. 1C; the B screen can rotate around the folding edge 1 together with the C screen according to the direction 13b shown in FIG. 1C. For example, in the half-folded state 2, the angle between the B screen and the C screen remains unchanged, the A screen rotates around the folding edge 1 according to the direction 13a, and / or the B screen rotates around the folding edge 1 according to the direction 13b, so that the folding screen can form the fully folded state shown in FIG. 1D.

[0091] As shown in FIG. 1D, the folding screen is in a fully folded state. In some embodiments, the folding screen can be folded from the half-folded state 1 shown in FIG. 1B or the half-folded state 2 shown in FIG. 1C to form the fully folded state. In the fully folded state, the angle between the A screen and the B screen is 0° or approximately 0°, and the angle between the B screen and the C screen is 0° or approximately 0°. The A screen and the B screen are opposite. The B screen and the C screen are opposite. In the fully folded state, the A screen is visible to the user, and the B screen and the C screen are not visible to the user, so that the electronic device 100 can use the A screen for display.

[0092] As shown in FIG. 1E, the folding screen is in a stand state. The stand state shown in FIG. 1E can be referred to as a stand state 1. In some embodiments, when the folding screen is in the fully unfolded state, the A screen rotates around the folding edge 1 according to the direction 11a, and the C screen rotates around the folding edge 2 according to the direction 11b, so that the folding screen can form the stand state 1. In the stand state 1, the angle α between the A screen and the B screen, and the angle β between the B screen and the C screen are both greater than 0° and less than 180°.

[0093] In some embodiments, in the stand state 1, the A screen rotates around the folding edge 1 according to the direction 14a shown in FIG. 1E, and the C screen rotates around the folding edge 2 according to the direction 14b shown in FIG. 1E, so that the folding screen can form the fully folded state shown in FIG. 1C. That is to say, the folding screen in the fully unfolded state can pass through the stand state 1 and be further folded to form the fully folded state.

[0094] FIGS. 2A and 2B exemplarily show folding state schematic diagrams of the tri-fold screen.

[0095] In some embodiments, according to the sizes of the included angle a and the included angle β, the folding states of the tri-fold screen can be divided into the following 9 folding states: a fully unfolded state, a fully folded state, a half-folded state 1, a half-folded state 2, a stand state 1, a stand state 2, a stand state 3, a stand state 4, and a stand state 5.

[0096] FIG. 2A shows the positional relationship among the A screen, the B screen, and the C screen when the folding screen is in the fully unfolded state, the fully folded state, the half-folded state 1, and the half-folded state 2. The fully unfolded state, the fully folded state, the half-folded state 1, and the half-folded state 2 can be referred to the foregoing descriptions of FIGS. 1A-1D. Here, no further description is given.

[0097] FIG. 2B shows the positional relationship among the A screen, the B screen, and the C screen when the folding screen is in the stand state 1 to the stand state 5. The stand state 1 can be referred to the foregoing description of FIG. 1E.

[0098] Regarding the stand state 2: when in the fully unfolded state, the A screen can rotate around the folding edge 1 in the direction 11a shown in FIG. 1A to form the stand state 2. Further, when in the stand state 2, the A screen continues to rotate around the folding edge 1 in a direction to reduce the included angle a, and the folding screen can finally form the half-folded state 1. That is to say, the folding screen in the fully unfolded state can fold through the stand state 2 and further fold to form the half-folded state 1. Conversely, the folding screen in the half-folded state 1 can unfold through the stand state 2 and finally form the fully unfolded state.

[0099] Regarding the stand state 3: when in the fully unfolded state, the C screen can rotate around the folding edge 2 in the direction 11b shown in FIG. 1A to form the stand state 3. Further, when in the stand state 3, the C screen continues to rotate around the folding edge 2 in a direction to reduce the included angle β, and the folding screen can finally form the half-folded state 2. That is to say, the folding screen in the fully unfolded state can fold through the stand state 3 and further fold to form the half-folded state 2. Conversely, the folding screen in the half-folded state 2 can unfold through the stand state 3 and finally form the fully unfolded state.

[0100] Regarding the stand state 4: when in the half-folded state 1, the angle between the A screen and the B screen remains unchanged, the B screen rotates around the folding edge 2 in the direction 12a shown in Fig. 1B, and / or, the C screen rotates around the folding edge 2 in the direction 12b shown in Fig. 1B, forming the stand state 4. Further, when in the stand state 4, the B screen and / or the C screen can continue to rotate around the folding edge 2 towards a direction that reduces the angle β, and the folding screens can finally form a fully folded state. That is, the folding screens in the half-folded state 1 can fold through the stand state 4 and further fold to form a fully folded state. Conversely, the folding screens in the fully folded state can unfold through the stand state 4 and finally form the half-folded state 1.

[0101] Regarding the stand state 5: when in the half-folded state 2, the angle between the B screen and the C screen remains unchanged, the A screen rotates around the folding edge 1 in the direction 13a shown in Fig. 1C, and / or, the B screen rotates around the folding edge 1 in the direction 13b shown in Fig. 1C, forming the stand state 5. Further, when in the stand state 5, the A screen and / or the B screen can continue to rotate around the folding edge 1 towards a direction that reduces the angle α, and the folding screens can finally form a fully folded state. That is, the folding screens in the half-folded state 2 can fold through the stand state 5 and further fold to form a fully folded state. Conversely, the folding screens in the fully folded state can unfold through the stand state 5 and finally form the half-folded state 2.

[0102] The following Table 1 exemplarily shows the range of values of the angle α and the angle β in each folding state.

[0103] Table 1

[0104] In some embodiments, when P1≤a≤180° and P2≤β≤180°, the electronic device 100 can determine that the folding screen is in a fully unfolded state. When 0°≤a≤P3 and P2≤β≤180°, the electronic device 100 can determine that the folding screen is in a half-folded state 1. When P1≤a≤180° and 0°≤β≤P4, the electronic device 100 can determine that the folding screen is in a half-folded state 2. When 0°≤a≤P3 and 0°≤β≤P4, the electronic device 100 can determine that the folding screen is in a fully folded state. When P3

[0105] In some embodiments, the folding screen of the electronic device 100 can be a complete screen of an integral structure. For example, the folding screen can be a flexible folding screen. The flexible folding screen includes a folding edge made of a flexible material. Part or all of the flexible folding screen is made of a flexible material. That is, the A screen, the B screen, and the C screen described above can be a complete screen of an integral structure.

[0106] In some embodiments, the folding screen of the electronic device 100 can be a multi-screen folding screen, which can be composed of a plurality of independent display screens. The plurality of display screens can be connected in sequence by folding shafts or hinges. Each display screen can rotate around the folding shaft or hinge connected thereto to realize folding of the multi-screen folding screen. That is, the A screen, the B screen, and the C screen described above can be independent display screens.

[0107] It should be noted that the names of the folding states described above are only exemplary descriptions of the present application and should not be construed as limiting the present application. For example, the half-folded state 1 described above can also be referred to as a half-unfolded state 1. The half-folded state 2 described above can also be referred to as a half-unfolded state 2. The stand states 1-5 described above can also be referred to as hovering states 1-5.

[0108] It can be seen that in the above fully unfolded state, half-folded state 1, half-folded state 2, and fully closed state, any two adjacent display screens (for example, A screen and B screen, or B screen and C screen) are in a fully unfolded state (that is, the included angle between the two display screens is 180° or approximately 180°), or in a fully folded state (that is, the included angle between the two display screens is 0° or approximately 0°). In the above support state 1 to support state 5, there are two adjacent display screens in a partially unfolded state. The above partially unfolded state is between the fully unfolded state and the fully folded state.

[0109] In some embodiments, the display screen used by the electronic device 100 for display can be different when the folding screen is in different folding states.

[0110] FIG. 3 exemplarily shows a display screen diagram used for display in different folding states.

[0111] As shown in FIG. 3, when the folding screen is in the fully unfolded state, the electronic device 100 can use one or more of the A screen, B screen, and C screen for display. That is, in the fully unfolded state, the A screen, B screen, and C screen can all be used for display. When the folding screen is in the half-folded state 1, the electronic device 100 can use the B screen and / or C screen for display. That is, in the half-folded state 1, the A screen can be in a powered-off state, and the B screen and C screen can both be used for display. When the folding screen is in the half-folded state 2 or the fully closed state, the electronic device 100 can use the A screen for display. That is, in the half-folded state 2 or the fully closed state, the B screen and C screen can both be in a powered-off state, and the A screen can be used for display.

[0112] The support states 1 to 5 shown in the foregoing FIG. 2B are intermediate states that the folding screen passes through in the process of switching between the fully unfolded state, half-folded state 1, half-folded state 2, and fully closed state.

[0113] In some embodiments, when the folding state of the folding screen changes to any one of the support states 1 to 5, the electronic device 100 can turn off the folding screen, that is, power off the A screen, B screen, and C screen. For example, in the scenario where the folding screen changes from the fully unfolded state to the half-folded state 1 through the support state 2, when changing to the support state 2, the electronic device 100 can power off the A screen, B screen, and C screen; when changing from the support state 2 to the half-folded state 1, the electronic device 100 can keep the A screen in a powered-off state and power on the B screen and C screen. For another example, in the scenario where the folding screen changes from the half-folded state 1 to the fully closed state through the support state 4, when changing to the support state 4, the electronic device 100 can keep the A screen in a powered-off state and power off the B screen and C screen; when changing from the support state 4 to the fully closed state, the electronic device 100 can keep the B screen and C screen in a powered-off state and power on the A screen.

[0114] One display screen can be divided into one or more display areas. In embodiments of the present application, powering on a display area can mean powering on the light-emitting devices in the display area on the display screen. Powering off a display area can mean powering off the light-emitting devices in the display area on the display screen.

[0115] In some embodiments, when the folding screen is in one of the folding states of support state 1 to support state 3, the electronic device 100 can use one or more of the A screen, the B screen, and the C screen for display. When the folding screen is in support state 4, the electronic device 100 can use the B screen and / or the C screen for display. When the folding screen is in support state 5, the electronic device 100 can use the A screen for display.

[0116] It should be noted that the display screens used for display in different folding states described above are only exemplary descriptions of the present application and should not be construed as limiting the present application.

[0117] The screen-off display method provided in embodiments of the present application can be applied to electronic devices with multi-fold screens. In subsequent embodiments, the screen-off display method is specifically described taking a three-fold screen as an example.

[0118] FIGS. 4A-4E exemplarily show some scenarios of screen-off display.

[0119] As shown in FIG. 4A, the folding screen of the electronic device 100 is in a fully unfolded state. After receiving a screen-off operation, the electronic device 100 can display AOD content at a preset position. Here, taking an example that the AOD content includes a butterfly image, the preset position can be the center position of the folding screen. Since the B screen is located between the A screen and the C screen, the center position of the folding screen can be the center position of the B screen.

[0120] As shown in FIG. 4A, the B screen is in a powered-on state, and the A screen and the C screen are in a powered-off state. The electronic device 100 can display the AOD content on the B screen.

[0121] In some embodiments, the electronic device 100 can capture an image through the front camera and detect the gaze direction of the human eye according to the captured image. The electronic device 100 can determine the gaze area of the human eye according to the gaze direction of the human eye. The electronic device 100 can move the AOD content to the gaze area of the human eye.

[0122] For example, when the gaze of the human eye is detected on the A screen, the electronic device 100 can move the AOD content from the B screen to the A screen.

[0123] As shown in FIG. 4B, the electronic device 100 can display an animation of the AOD content gradually moving from the B screen to the A screen. For example, the AOD content includes a butterfly image. The animation of the AOD content gradually moving from the B screen to the A screen can include an animation of the butterfly flying from the B screen to the A screen.

[0124] In some embodiments, when the human eye gaze A is detected, the electronic device 100 can keep the B screen in the powered-on state and power on the A screen. As shown in FIG. 4C, after the animation of moving the AOD content from the B screen to the A screen is played, the electronic device 100 can power off the B screen and keep the A screen in the powered-on state.

[0125] In some embodiments, during the process of displaying the animation of moving the AOD content from the B screen to the A screen, the AOD content on the folding screen can have the following three display situations: situation 11, the AOD content is all displayed on the B screen; situation 12, the AOD content is partially displayed on the B screen and the other part of the content is displayed on the A screen; and situation 13, the AOD content is all displayed on the B screen. Among them, when the AOD content moves to the A screen that needs to be displayed, the electronic device 100 can power on the A screen. When the AOD content moves to all be displayed on the A screen, the electronic device 100 can power off the B screen. That is, in the above-mentioned situation 11, only the B screen in the electronic device 100 is in the powered-on state. In the above-mentioned situation 12, the A screen and the B screen are both in the powered-on state. In the above-mentioned situation 13, only the A screen in the electronic device 100 is in the powered-on state.

[0126] In some embodiments, in the case of displaying the AOD content on the B screen as shown in FIG. 4A, the part of the B screen for displaying the AOD content can be in the powered-on state, and the other part of the B screen without displaying the AOD content can be in the powered-off state. In addition, when the AOD content needs to be moved from the B screen to the A screen, the electronic device 100 can power on the part of the A screen for displaying the AOD, and the other part of the A screen without displaying the AOD content can continue to remain in the powered-off state. In this way, the power consumption of the electronic device 100 can be reduced.

[0127] In some embodiments, the electronic device 100 can be provided with a loudspeaker in the part where the A screen is located. The loudspeaker can be referred to as the left loudspeaker of the electronic device 100. The animation of moving the AOD content from the B screen to the A screen can be accompanied by a transition sound effect. For example, in the process of moving the AOD content from the B screen to the A screen as shown in FIG. 4B, the electronic device 100 can play audio 1 through the left loudspeaker.

[0128] Optionally, the electronic device 100 can be provided with a speaker in the part where the C screen is located. The speaker can be referred to as the right speaker of the electronic device 100. In the process of gradually moving the AOD content from the B screen to the A screen, the electronic device 100 can first play audio 1 using the left speaker and the right speaker, and then gradually transition to playing audio 1 using only the left speaker. Specifically, when the AOD content is still displayed on the B screen, the electronic device 100 can play audio 1 using the left speaker and the right speaker. As the AOD content moves to the left, the loudness of the audio 1 played by the right speaker of the electronic device 100 can gradually decrease, and the loudness of the audio 1 played by the left speaker of the electronic device 100 can gradually increase. When the AOD content moves to the A screen, the electronic device 100 can turn off the right speaker and play audio 1 using only the left speaker. In this way, the transition sound effect can change with the movement of the AOD content, improving the user experience of using the AOD.

[0129] In some embodiments, without moving the AOD content, the electronic device 100 can refresh the display of the AOD content at a frame rate 1. In the process of moving the AOD content and displaying the animation of the movement of the AOD content, the electronic device 100 can increase the frame rate to refresh the display of the AOD content at a frame rate 2. After the AOD content moves to the target display area, the electronic device 100 can reduce the frame rate to the frame rate 1 and continue to display the AOD content in the target display area at the frame rate 1. The present application does not limit the values of the frame rate 1 and the frame rate 2. For example, the frame rate 1 can be 1 hertz (hz). The frame rate 2 can be 30 hz. In this way, the display effect of the AOD content movement animation in the process of moving the AOD content can be improved, and the power consumption of the electronic device 100 can be reduced when the AOD content does not need to move the display area.

[0130] In some embodiments, when the human eye is detected to gaze at the A screen, the electronic device 100 can power off the B screen and power on the A screen. After powering on the A screen, the electronic device 100 can display the AOD content on the A screen. That is, when changing the display area of the AOD content, the electronic device 100 can directly display the AOD content on the target display area (for example, the center area of the A screen), without playing the animation of gradually moving the AOD content from the original display area to the target display area. The above-mentioned target display area can be determined according to the gaze direction of the human eye.

[0131] As shown in FIG. 4C, the AOD content is displayed on the A screen. When the electronic device 100 detects that the human eye gazes at the C screen, the electronic device 100 can move the AOD content from the A screen to the C screen.

[0132] As shown in FIG. 4D, the electronic device 100 can display an animation of the content of the AOD gradually moving from the A-screen to the C-screen. For example, the AOD content includes a butterfly image. The animation of the AOD content gradually moving from the A-screen to the C-screen can include an animation of the butterfly flying from the A-screen to the C-screen, passing through the B-screen, and finally flying to the C-screen.

[0133] In some embodiments, when the human eye gaze is detected on the C-screen, the electronic device 100 can keep the A-screen in the powered-on state, and power on the B-screen and the C-screen. As shown in FIG. 4E, after the animation of the AOD content moving from the A-screen to the C-screen is played, the electronic device 100 can power off the A-screen and the B-screen, and keep the C-screen in the powered-on state.

[0134] In some embodiments, during the display of the animation of the AOD content gradually moving from the A-screen to the C-screen, the AOD content can have the following five display situations on the folding screen: situation 21, the AOD content is displayed entirely on the A-screen; situation 22, the AOD content is partially displayed on the A-screen and partially displayed on the B-screen; situation 23, the AOD content is displayed entirely on the B-screen; situation 24, the AOD content is partially displayed on the B-screen and partially displayed on the C-screen; and situation 25, the AOD content is displayed entirely on the C-screen. When the AOD content moves to need to be displayed on the B-screen, the electronic device 100 can power on the B-screen. When the AOD content moves to be displayed entirely on the B-screen, the electronic device 100 can power off the A-screen. When the AOD content moves to need to be displayed on the C-screen, the electronic device 100 can power on the C-screen. When the AOD content moves to be displayed entirely on the C-screen, the electronic device 100 can power off the B-screen. That is, in the above-mentioned situation 21, only the A-screen in the electronic device 100 is in the powered-on state. In the above-mentioned situation 22, the A-screen and the B-screen in the electronic device 100 are in the powered-on state, and the C-screen is in the powered-off state. In the above-mentioned situation 23, only the B-screen in the electronic device 100 is in the powered-on state. In the above-mentioned situation 24, the B-screen and the C-screen in the electronic device 100 are in the powered-on state, and the A-screen is in the powered-off state. In the above-mentioned situation 25, only the C-screen in the electronic device 100 is in the powered-on state.

[0135] As can be seen, during the process of the AOD content gradually moving from the A-screen to the C-screen, the B-screen and the C-screen can be powered on according to the moving position of the AOD content. The electronic device 100 can power on the display screen that needs to display the AOD content according to the moving situation of the AOD content. In this way, the A-screen, the B-screen, and the C-screen can not all be in the powered-on state during the process of the AOD content moving from the A-screen to the C-screen, thereby reducing the power consumption of the electronic device 100.

[0136] In some embodiments, the electronic device 100 can be provided with a speaker in the portion where the C screen is located. The speaker can be referred to as the right speaker of the electronic device 100. The animation of the gradual movement of the AOD content from the A screen to the C screen can be accompanied by a transition sound effect. For example, during the gradual movement of the AOD content from the A screen to the C screen as shown in FIG. 4D, the electronic device 100 can play the audio 2 through the right speaker.

[0137] Optionally, during the gradual movement of the AOD content from the A screen to the C screen, the electronic device 100 can first play the audio 2 through the left speaker and then gradually transition to playing the audio 2 through the right speaker. Specifically, when the AOD content is still displayed on the A screen, the electronic device 100 can play the audio 2 through the left speaker. As the AOD content moves to the right, the loudness of the audio 2 played by the left speaker of the electronic device 100 can gradually decrease. When the AOD content moves to the B screen, the electronic device 100 can play the audio 2 through both the left speaker and the right speaker. Further, as the AOD content continues to move to the right, the loudness of the audio 2 played by the right speaker of the electronic device 100 can gradually increase. When the AOD content moves to the C screen, the electronic device 100 can turn off the left speaker and play the audio 2 through the right speaker. In this way, the transition sound effect can change with the movement of the AOD content, improving the user experience of using the AOD.

[0138] The embodiments of the present application do not limit the speaker used by the electronic device 100 to play the audio during the movement of the AOD content.

[0139] In some embodiments, when the AOD content is displayed on the A screen, the electronic device 100 can turn off the A screen, turn on the C screen, and keep the B screen in the off state when detecting that the human eye gazes at the C screen. After turning on the C screen, the electronic device 100 can display the AOD content on the C screen.

[0140] In some embodiments, the AOD content is a dynamic AOD. The dynamic AOD can include multiple frames of images. When the electronic device 100 displays the dynamic AOD in a display area, the electronic device 100 can display the multiple frames of images included in the dynamic AOD in a loop in the display area. When an event triggering the electronic device 100 to move the AOD content from the display area 1 to the display area 2 is detected, the electronic device 100 can continue to display the dynamic AOD on the display area 2 according to the display state of the current dynamic AOD on the display area 1. In this way, the continuity of the display of the dynamic AOD before and after the movement can be achieved, improving the user experience of watching the AOD.

[0141] For example, the dynamic AOD includes 6 frames of images: 1st frame of image ~ 6th frame of image. The electronic device 100 can display the 6 frames of images in the order of 1st frame of image ~ 6th frame of image on display area 1 in a loop. If the electronic device 100 detects the user's gaze on display area 2 while displaying the 2nd frame of image in the 6 frames of images on display area 1, the electronic device 100 can move the AOD content to display area 2. Here, the electronic device 100 can first display the 3rd frame of image in the 6 frames of images on display area 2, and display the 6 frames of images in the order of 1st frame of image ~ 6th frame of image on display area 2 in a loop. Further, if the electronic device 100 detects the user's gaze on display area 3 while displaying the 4th frame of image in the 6 frames of images on display area 2, the electronic device 100 can move the AOD content to display area 3. Here, the electronic device 100 can first display the 4th frame of image in the 6 frames of images on display area 3, and display the 6 frames of images in the order of 1st frame of image ~ 6th frame of image on display area 3 in a loop.

[0142] The display area 1, display area 2, and display area 3 can be any display area on one or more of the A screen, B screen, and C screen. The display area 1, display area 2, and display area 3 can be completely different, or there can be an area partially overlapping.

[0143] As can be seen from the scenarios of FIGS. 4A-4E, the electronic device 100 can move the AOD content between the three display screens included in the foldable screen according to changes in the direction of the gaze of the human eye. When the direction of the gaze of the human eye changes from left to right, the display position of the AOD content can move to the right (for example, from the A screen to the C screen as shown in FIG. 4D). When the direction of the gaze of the human eye changes from right to left, the display position of the AOD content can move to the left (for example, from the B screen to the A screen as shown in FIG. 4B). This can improve the interactivity of the AOD content, and the user can move the AOD content on each display area of the screen by changing the direction of the gaze. In addition, the electronic device 100 can display an animation of the movement of the AOD content in the process of moving the AOD content. This animation can provide stronger interactivity for the user, and the user can better perceive the process of the movement of the AOD content according to changes in the direction of the gaze of the human eye. This can improve the user experience of the user using the AOD on the electronic device 100.

[0144] In some embodiments, the electronic device 100 can move the AOD content between different display areas of one display screen according to changes in the direction of the gaze of the human eye.

[0145] FIGS. 5A-5C exemplarily show some scenarios of screen-off display.

[0146] As shown in FIG. 5A, the B screen of the electronic device 100 can include a region 511 and a region 512. The AOD content is currently displayed in the region 511. Among them, the B screen is in a powered-on state. Both the A screen and the C screen can be in a powered-off state. The electronic device 100 can capture an image through the front camera, and detect the gaze direction of the human eye according to the captured image.

[0147] For example, when the gaze region 512 of the human eye is detected, the electronic device 100 can move the AOD content from the region 511 to the region 512.

[0148] As shown in FIG. 5B, the electronic device 100 can display an animation in which the AOD content gradually moves from the region 511 to the region 512. For example, the AOD content includes a butterfly image. The animation in which the AOD content gradually moves from the region 511 to the region 512 can include an animation in which the butterfly flies from the region 511 to the region 512. Optionally, the electronic device 100 can play corresponding audio during the movement of the AOD content, to provide a transition sound effect of the AOD movement to the user.

[0149] As shown in FIG. 5C, when the AOD content moves to the region 512 and the gaze direction of the human eye does not change, the AOD content can be kept displayed in the region 512.

[0150] In some embodiments, when the AOD content is displayed in any region of the B screen, all regions of the B screen can be in a powered-on state. That is, during the movement of the AOD content between different regions of the B screen, the electronic device 100 can not need to change the power-on and power-off states of the A screen, the B screen, and the C screen.

[0151] Alternatively, the region of the B screen in which the AOD content is displayed can be in a powered-on state. Another part of the region of the B screen in which the AOD content is not displayed can be in a powered-off state. For example, in the case where the AOD content is displayed in the region 511 as shown in FIG. 5A, the region 511 can be in a powered-on state. Other regions (for example, the region 512) of the B screen other than the region 511 can be in a powered-off state. As shown in FIG. 5B, when the AOD content moves to the region 512, the electronic device 100 can power on the region 512. As shown in FIG. 5C, when the AOD content moves out of the region 511, the electronic device 100 can power off the region 511.

[0152] The above-mentioned region 511 and region 512 are only exemplary descriptions of the present application, and should not be construed as limiting the present application. The AOD content can also move between other regions. For example, the AOD content can move from the region 511 to a region between the A screen and the B screen. The region between the A screen and the B screen simultaneously contains a part of the A screen and a part of the B screen, i.e., a region on the folding edge 1.

[0153] It can be seen that the electronic device 100 can move the AOD content according to the change of the gaze direction of the human eye. Among them, the AOD content can not only be moved between different display screens contained by the folding screen, but also be moved between different display areas on one display screen contained by the folding screen. For example, in the case where the AOD content is displayed in the center of the B screen, when the gaze direction of the human eye changes from up, the display position of the AOD content can be moved up (for example, from the area 511 to the area 512 as shown in FIG. 5B); or when the gaze direction of the human eye changes downward, the AOD content can be moved downward. Among them, the greater the distance of the change of the gaze direction of the human eye, the greater the distance of the movement of the AOD content can be.

[0154] That is to say, the AOD content can be moved between any areas of the folding screen according to the change of the gaze direction of the human eye. In this way, the accuracy of the movement of the AOD content position can be improved, and the interactivity between the user and the AOD content can be better improved.

[0155] FIGS. 6A-6E exemplarily show some screen-off display scene schematic diagrams.

[0156] As shown in FIG. 6A, the folding screen of the electronic device 100 is in a fully unfolded state. After receiving the screen-off operation, the electronic device 100 can display the AOD content at a preset position. For example, the above-mentioned preset position can be the center position of the B screen.

[0157] As shown in FIG. 6A, the B screen is in a powered-on state, and the A screen and the C screen are in a powered-off state. The electronic device 100 can display the AOD content on the B screen.

[0158] In some embodiments, in the screen-off display state, the electronic device 100 can detect a click operation acting on the display screen. The electronic device 100 can move the AOD content to the position where the click operation acts.

[0159] For example, when detecting a click operation acting on the A screen, the electronic device 100 can move the AOD content from the B screen to the A screen.

[0160] As shown in FIG. 6B, the electronic device 100 can display an animation of the AOD content gradually moving from the B screen to the A screen. For example, the AOD content includes a butterfly image. The above-mentioned animation of the AOD content gradually moving from the B screen to the A screen can include an animation of the butterfly flying from the B screen to the A screen. The method of the electronic device 100 powering on and off the folding screen when the AOD content moves from the B screen to the A screen can refer to the foregoing description of FIGS. 4A-4C. Here, no longer be described.

[0161] In some embodiments, the click operation shown in FIG. 6A can be a click operation acting on any position of the A screen. When it is needed to move the AOD content to the A screen, the electronic device 100 can move the AOD content to a preset position on the A screen. The preset position on the A screen is not limited in the embodiments of the present application. For example, the preset position on the A screen can be the center position of the A screen. That is to say, in response to the click operation acting on any position of the A screen, the electronic device 100 can move the AOD content to the center position of the A screen.

[0162] As shown in FIG. 6C, the AOD content is displayed on the A screen. When the click operation acting on the C screen is detected, the electronic device 100 can move the AOD content from the A screen to the C screen.

[0163] As shown in FIG. 6D, the electronic device 100 can display an animation of the AOD content gradually moving from the A screen to the C screen. For example, the AOD content includes a butterfly image. The animation of the AOD content gradually moving from the A screen to the C screen can include an animation of the butterfly flying from the A screen to the direction of the C screen, passing through the B screen and finally flying to the C screen.

[0164] As shown in FIG. 6E, after the AOD content is moved to the C screen, the electronic device 100 can power off the A screen and the B screen. The method of powering off the folding screen when the AOD content moves from the A screen to the C screen can refer to the foregoing description of FIGS. 4C-4E. Here, no longer be described in detail.

[0165] In some embodiments, the click operation shown in FIG. 6C can be a click operation acting on any position of the C screen. When it is needed to move the AOD content to the C screen, the electronic device 100 can move the AOD content to a preset position on the C screen. The preset position on the C screen is not limited in the embodiments of the present application. For example, the preset position on the C screen can be the center position of the C screen. That is to say, in response to the click operation acting on any position of the C screen, the electronic device 100 can move the AOD content to the center position of the C screen.

[0166] It needs to be explained that the powering off of the display screen in the embodiments of the present application can refer to powering off the light emitting device (such as light emitting diode, backlight source, etc.) in the display screen. In some embodiments, in the case of powering off the display screen, the device (such as touch sensor) for detecting the click operation arranged on the display screen can still be in working state and not be powered off. In this way, even if the display screen is powered off, the electronic device 100 can also detect the click operation acting on the display screen.

[0167] As can be seen from the scenarios of FIGS. 6A-6E, the electronic device 100 can move the AOD content between the three display screens contained in the folding screen according to the detected click operation on the display screen. The user can change the display position of the AOD by touching different display screens. The above embodiments can improve the interactivity of the AOD content.

[0168] In some embodiments, in the screen-off display state, the electronic device 100 can move the AOD content between different display areas of one display screen according to the detected click operation.

[0169] FIGS. 7A-7C exemplarily show some screen-off display scenarios.

[0170] As shown in FIG. 7A, the electronic device 100 displays the AOD content at a position 711 of the B screen. When a click operation acting on a position 712 of the B screen is detected, the electronic device 100 can move the AOD content from the position 711 to the position 712. The position 712 can be any position on the B screen except the position 711.

[0171] As shown in FIG. 7B, the electronic device 100 can display an animation of the AOD content gradually moving from the position 711 to the position 712. For example, the AOD content includes a butterfly image. The animation of the AOD content gradually moving from the position 711 to the position 712 can include the butterfly flying from the position 711 to the position 712. Optionally, during the movement of the AOD content, the electronic device 100 can play corresponding audio to provide the user with a transition sound effect of the AOD movement.

[0172] As shown in FIG. 7C, when the AOD content moves to the position 712 and the electronic device 100 does not detect a new click operation, the AOD content can remain displayed at the position 712.

[0173] As can be seen, in the screen-off display state, the electronic device 100 can move the AOD content from the currently displayed position to the position of the click operation. For example, in the case that the AOD content is displayed at the center of the B screen, in response to a click operation acting on the top of the A screen, the electronic device 100 can move the AOD content from the center of the B screen to the top of the A screen. For another example, in the case that the AOD content is displayed at the top of the A screen, in response to a click operation acting on the bottom of the C screen, the electronic device 100 can move the AOD content from the top of the A screen to the bottom of the C screen.

[0174] As can be seen from the above scenarios, the AOD content can be moved between any areas of the folding screen based on the position of the user's click operation. This can improve the accuracy of the position movement of the AOD content and better improve the interactivity of the user and the AOD content.

[0175] It is to be noted that the aforementioned scenarios in which the AOD content moves are merely illustrative of the present disclosure. In the present disclosure, the AOD content can move between any display area on the screen currently used for display by the electronic device 100. The display area of the AOD content before the movement can be a display area composed of one or more display screens, or can be a partial display area on one display screen. The display area of the AOD content after the movement can be a display area composed of one or more display screens, or can be a partial display area on one display screen.

[0176] For example, the screen used for display by the electronic device 100 when the folding screen is in the fully unfolded state can include the A screen, the B screen, and the C screen. In the case where the AOD content is displayed in a display area composed of the A screen and the B screen (e.g., the location where the folding edge 1 is located), according to an event of moving the AOD content, the electronic device 100 can move the AOD content to a display area composed of the B screen and the C screen (e.g., the location where the folding edge 2 is located).

[0177] FIGS. 8A to 8E exemplarily illustrate some scenarios of the screen-off display.

[0178] As shown in FIG. 8A, the folding screen of the electronic device 100 is in the half-folded state 1. The electronic device 100 can display the AOD content using the B screen and / or the C screen. In the case where the folding screen is in the half-folded state 1, upon receiving the screen-off operation, the electronic device 100 can display the AOD content at a preset location. For example, the aforementioned preset location can be the center location of the display screen composed of the B screen and the C screen.

[0179] As shown in FIG. 8A, both the B screen and the C screen are in the powered-on state. The electronic device 100 can display the AOD content at the center location of the display screen composed of the B screen and the C screen. That is, a part of the AOD content can be displayed on the B screen. Another part of the AOD content can be displayed on the C screen.

[0180] It is to be noted that, when the folding screen is in the half-folded state 1, the A screen can always be in the powered-off state.

[0181] In some embodiments, in the screen-off display state, the electronic device 100 can detect a click operation acting on the display screen. The electronic device 100 can move the AOD content to the location where the click operation acts.

[0182] For example, when a click operation acting on the B screen is detected, the electronic device 100 can move the AOD content from between the B screen and the C screen to be fully displayed on the B screen.

[0183] As shown in FIG. 8B, the electronic device 100 can display an animation of the AOD content moving. For example, the AOD content includes a butterfly image. The animation of the AOD content moving can include an animation of the butterfly flying from the folding edge 2 to the left to be completely located on the B screen.

[0184] In some embodiments, when the AOD content is completely moved to the B screen, the electronic device 100 can power off the C screen.

[0185] As shown in FIG. 8C, the B screen is in a powered-on state and the C screen is in a powered-off state. In the case where no new click operation is received, the electronic device 100 can keep displaying the AOD content on the B screen.

[0186] As shown in FIG. 8C, in the case where the AOD content is displayed on the B screen, in response to a click operation acting on the C screen, the electronic device 100 can move the AOD content from the B screen to the C screen.

[0187] As shown in FIG. 8D, the electronic device 100 can display an animation of the AOD content gradually moving from the B screen to the C screen. For example, the AOD content includes a butterfly image. The animation of the AOD content gradually moving from the B screen to the C screen can include an animation of the butterfly flying from the B screen to the right to the C screen.

[0188] In some embodiments, when a click operation acting on the C screen is detected, the electronic device 100 can power on the C screen. When the animation of the AOD content gradually moving from the B screen to the C screen is played, the electronic device 100 can power off the B screen. Alternatively, when the AOD content is moved to be displayed on the C screen, the electronic device 100 can power on the C screen. When the AOD content is moved out of the B screen, the electronic device 100 can power off the B screen.

[0189] As shown in FIG. 8E, the C screen is in a powered-on state, and in the case where no new click operation is received, the electronic device 100 can keep displaying the AOD content on the C screen. After the electronic device 100 powers off the B screen, the B screen can be in a powered-off state.

[0190] In some embodiments, in the half-folded state 1, the electronic device 100 can move the AOD content from a currently displayed position to a preset position (for example, the preset position can be a center position of the screen) on the B screen (or the C screen) in response to a click operation acting on any position of the B screen (or the C screen). Alternatively, in the half-folded state 1, the electronic device 100 can move the AOD content from a currently displayed position to a position where the click operation acts in response to a click operation acting on any position of the B screen (or the C screen). In this way, the AOD content can be moved to any position on the B screen and the C screen. For details, reference can be made to the foregoing descriptions of FIGS. 7A-7C.

[0191] In some embodiments, during the movement of the AOD content shown in FIGS. 8A-8E, the electronic device 100 can play corresponding audio to provide a transition sound effect of the AOD movement to the user.

[0192] In some embodiments, the front camera of the electronic device 100 is arranged on the A screen. When the folding screen is in the half-folded state 1, the display screen viewed by the user is usually the B screen and the C screen, and the front camera on the A screen cannot capture the face image of the user. Therefore, the user interaction mode with the AOD content can include changing the display position of the AOD content by a click operation, but does not include changing the display position of the AOD content by changing the gaze direction of the human eye. Wherein, when the folding screen is in the half-folded state 1, the front camera arranged on the A screen can be in a non-working state.

[0193] In some embodiments, a camera is arranged on the B screen and / or the C screen of the electronic device 100. When the folding screen is in the half-folded state 1, the electronic device 100 can capture the image of the user through the camera on the B screen and / or the C screen, and identify the gaze direction of the human eye of the user according to the captured image. Then, the electronic device 100 can change the display position of the AOD content on the B screen and the C screen according to the change of the gaze direction of the human eye. In this way, in the half-folded state 1, the user can change the display position of the AOD content by both a click operation and changing the gaze direction of the human eye.

[0194] From the above scenario, it can be known that when the folding screen of the electronic device 100 is in the half-folded state 1, the AOD content displayed after the electronic device 100 is turned off can also interact with the user. For example, according to the click operation of the user, the electronic device 100 can move the AOD content on the B screen and the C screen at will. In this way, the interactivity between the user and the AOD content can be improved, and the user experience of the user using the electronic device 100 in the half-folded state 1 can be improved.

[0195] In some embodiments, not limited to the fully unfolded state and the half-folded state 1, when the folding screen of the electronic device 100 is in the half-folded state 2 or the fully folded state, the electronic device 100 can also change the display position of the AOD content according to the event (such as a touch operation on the display area, a gaze area of the human eye on the screen) used to trigger the movement of the AOD content.

[0196] From the foregoing embodiment of FIG. 3, it can be known that in the half-folded state 2 and the fully folded state, the electronic device 100 can use the A screen for display, and keep the B screen and the C screen in a powered-off state. The front camera is arranged on the A screen.

[0197] In the case that the folding screen is in the half-folded state 2 and the fully folded state, after the electronic device 100 receives a turn-off operation, the electronic device 100 can display the AOD content on the A screen.

[0198] In some embodiments, in the screen-off display state, the electronic device 100 can capture an image through the front camera on the A-screen, and identify the gaze direction of the human eye of the user. The electronic device 100 can move the AOD content on the A-screen according to the change of the gaze direction of the human eye. For example, when the gaze direction of the human eye moves upward, the electronic device 100 can move the AOD content upward on the A-screen. When the gaze direction of the human eye moves downward, the electronic device 100 can move the AOD content downward on the A-screen.

[0199] In some embodiments, in the screen-off display state, the electronic device 100 can move the AOD content to the position of the click operation acting on the A-screen according to the click operation. In this way, the user can touch any position on the A-screen to change the display position of the AOD content on the A-screen.

[0200] In some embodiments, during the movement of the AOD content on the A-screen, the electronic device 100 can play corresponding audio to provide the user with the transition sound effect of the AOD movement.

[0201] In some embodiments, when the folding screen is in the half-folded state 2 or the fully folded state, the electronic device 100 can power on the part of the A-screen displaying the AOD content and power off the other part of the A-screen not displaying the AOD content in the screen-off display state. When the AOD content moves on the A-screen, the electronic device 100 can adjust the areas in the A-screen that are powered on and powered off according to the movement of the AOD content. In this way, the power consumption of the electronic device 100 in the screen-off display state can be reduced.

[0202] As can be seen, in any one of the fully unfolded state, the fully folded state, the half-folded state 1, and the half-folded state 2 of the folding screen, the electronic device 100 can move the AOD content in part or all of the display area of the folding screen according to the event (such as the touch operation on the display area and / or the gaze area of the human eye on the screen) for triggering the movement of the AOD content. In this way, the interactivity of the AOD content can be improved, thereby improving the user experience of the user using the AOD on the folding screen device.

[0203] FIG. 9 illustrates a flowchart of a screen-off display method provided by the present application.

[0204] S911, the electronic device 100 detects a screen-off event.

[0205] In some embodiments, the screen-off event can include a screen-off operation acting on the electronic device 100. For example, the screen-off operation can include an operation of pressing a power button when the electronic device 100 is in a screen-on state. Alternatively, the screen-off event can also include that no user operation acts on the display screen within a preset time period in the screen-on state. The preset time period can be 5 minutes or 10 minutes, etc. Embodiments of the present application do not limit the value of the preset time period.

[0206] When the AOD function is enabled, the screen-off event can be used to trigger the electronic device 100 to enter the AOD state. Embodiments of the present application do not limit the screen-off event.

[0207] S912, when the folding screen is in the first folding state, the electronic device 100 can display AOD content in the display area a1 according to a preset AOD theme. When the display area a1 displays AOD content, other display areas except the display area a1 are in a powered-off state.

[0208] The electronic device 100 can determine that the display area for AOD display is the display area a1 according to the folding state of the folding screen.

[0209] In some embodiments, when the screen-off event triggering the folding screen to be in a screen-off state is detected, the electronic device 100 can detect the folding state of the folding screen and determine the display area for AOD display according to the folding state.

[0210] The electronic device 100 can be provided with a gyroscope sensor. The electronic device 100 can detect the folding state of the folding screen through the gyroscope sensor. The folding screen can include the three display screens A, B and C shown in FIG. 1A. The gyroscope sensor can be arranged on each of the display screens A, B and C to measure the orientation of the corresponding display screen. The electronic device 100 can determine the included angle between two adjacent display screens, such as the included angle between the display screens A and B and the included angle between the display screens B and C, according to the change of the orientation angle of each display screen measured by the gyroscope sensor. In this way, based on the foregoing description of the relationship between the included angle between two adjacent display screens and the folding state in FIG. 2A and FIG. 2B, the electronic device 100 can determine the folding state of the folding screen.

[0211] Optionally, the electronic device 100 can be provided with an angle sensor. The electronic device 100 can detect the folding state of the folding screen through the angle sensor. The folding screen can include the three display screens A, B and C shown in FIG. 1A. The folding edge between the A screen and the B screen is folding edge 1. The folding edge between the B screen and the C screen is folding edge 2. The angle sensor can be arranged at the positions of the folding edge 1 and the folding edge 2. The electronic device 100 can detect the included angle between the A screen and the B screen based on the angle sensor at the position of the folding edge 1, and detect the included angle between the B screen and the C screen based on the angle sensor at the position of the folding edge 2. In this way, based on the foregoing description of the relationship between the included angle between two adjacent display screens and the folding state in FIGS. 2A and 2B, the electronic device 100 can determine the folding state of the folding screen.

[0212] Optionally, the electronic device 100 can be provided with a magnetic sensor. The electronic device 100 can detect the folding state of the folding screen through the magnetic sensor. The folding screen can include the three display screens A, B and C shown in FIG. 1A. In some embodiments, the A screen and the C screen can be provided with a magnetic sensor, and the B screen can be provided with a magnet. The greater the included angle between the A screen and the B screen, the farther the distance between the magnetic sensor on the A screen and the magnet on the B screen, and the smaller the magnetic flux detected by the magnetic sensor on the A screen. Similarly, the greater the included angle between the B screen and the C screen, the farther the distance between the magnetic sensor on the C screen and the magnet on the B screen, and the smaller the magnetic flux detected by the magnetic sensor on the C screen. The electronic device 100 can determine the folding state of the folding screen according to the magnetic flux detected by the magnetic sensor on the A screen and the magnetic flux detected by the magnetic sensor on the C screen. For example, if the magnetic flux detected by the magnetic sensor on the A screen is less than a magnetic flux threshold 1, and the magnetic flux detected by the magnetic sensor on the C screen is less than a magnetic flux threshold 2, the electronic device 100 can determine that the folding screen is in a fully unfolded state. The present application does not limit the values of the magnetic flux threshold 1 and the magnetic flux threshold 2.

[0213] Optionally, the electronic device 100 can detect the folding state of the folding screen through the touch sensor on the folding screen. The folding screen can include the three display screens A, B and C shown in FIG. 1A. The folding edge between the A screen and the B screen is folding edge 1. The folding edge between the B screen and the C screen is folding edge 2. The capacitance value detected by the touch sensor in the area of the folding edge can change with the angle between the display screens on both sides of the folding edge. The smaller the angle between the display screens on both sides of the folding edge, the greater the capacitance value detected by the touch sensor in the area of the folding edge. For example, the electronic device 100 can determine whether the A screen and the B screen are folded according to whether the capacitance value detected by the touch sensor in the area of the folding edge 1 is greater than a capacitance threshold 1. The electronic device 100 can determine whether the B screen and the C screen are folded according to whether the capacitance value detected by the touch sensor in the area of the folding edge 2 is greater than a capacitance threshold 2. The present application does not limit the values of the capacitance threshold 1 and the capacitance threshold 2.

[0214] Without being limited to the above method of determining the folding state, the electronic device 100 can also detect the folding state of the folding screen through other methods.

[0215] As shown in FIG. 3, the display screen used by the electronic device 100 for display is related to the folding state of the folding screen. The first folding state can be any one of the fully unfolded state, the half-folded state 1, the half-folded state 2, and the fully folded state.

[0216] For example, if the folding screen is in the fully unfolded state, the display screen used by the electronic device 100 for display can be one or more of the A screen, the B screen and the C screen. In the fully unfolded state, in response to the screen-off event, the electronic device 100 can display the AOD content on the B screen (see FIG. 4A). That is, the display area a1 can be the display area corresponding to the B screen.

[0217] If the folding screen is in the half-folded state 1, the display screen used by the electronic device 100 for display can be the B screen and / or the C screen. In the half-folded state 1, in response to the screen-off event, the electronic device 100 can display the AOD content on the B screen and the C screen (see FIG. 8A). That is, the display area a1 can be the display area corresponding to the B screen and the C screen.

[0218] If the folding screen is in the half-folded state 2 or the fully folded state, the display screen used by the electronic device 100 for display can be the A screen. In the half-folded state 2 or the fully folded state, in response to the screen-off event, the electronic device 100 can display the AOD content on the A screen. That is, the display area a1 can be the display area corresponding to the A screen.

[0219] It should be noted that the display area a1 can be a display area in which the electronic device 100 first displays AOD content after entering the screen-off display state. Thereafter, the electronic device 100 can change the display area of the AOD content according to an event for triggering movement of the AOD content.

[0220] Optionally, the first folding state can also be any one of the stand states 1 to 5.

[0221] In some embodiments, in response to the screen-off event, the electronic device 100 can power off all display areas (i.e., the A screen, the B screen, and the C screen) of the folding screen. Then, the electronic device 100 can power on the display area a1 and display AOD content on the display area a1. Alternatively, in response to the screen-off event, the electronic device 100 can keep the display area a1 powered on and power off other display areas except the display area a1.

[0222] For example, when the folding screen is in the fully unfolded state, the display area a1 can be a display area corresponding to the B screen. The electronic device 100 can power on the B screen and power off the A screen and the C screen. Alternatively, when the folding screen is in the fully unfolded state, the display area a1 can be a part of the display area on the B screen (e.g., a part of the display area where the center of the B screen is located). The electronic device 100 can power on the display area a1, power off the display area on the B screen except the display area a1, and power off the A screen and the C screen.

[0223] When the folding screen is in the half folding state 1, the display area a1 can be a display area corresponding to the B screen and the C screen. The electronic device 100 can power on the B screen and the C screen and keep the A screen in the powered-off state. Alternatively, when the folding screen is in the half folding state 1, the display area a1 can be composed of a part of the display area on the B screen and a part of the display area on the C screen. The electronic device 100 can power on the display area a1, power off the display area on the B screen and the C screen except the display area a1, and keep the A screen in the powered-off state.

[0224] When the folding screen is in the half folding state 2 or the fully folded state, the display area a1 can be a display area corresponding to the A screen. The electronic device 100 can power on the A screen and keep the B screen and the C screen in the powered-off state. Alternatively, when the folding screen is in the half folding state 2 or the fully folded state, the display area a1 can be a part of the display area on the A screen (e.g., a part of the display area where the center of the A screen is located). The electronic device 100 can power on the display area a1, power off the display area on the A screen except the display area a1, and keep the B screen and the C screen in the powered-off state.

[0225] In some embodiments, the powering off the display area by the electronic device 100 can include turning off one or more signals of a screen driving P start vertical (GSTV), a screen driving N start vertical (NSTV), a signal toggle, and the like in the display area. The powering on the display area by the electronic device 100 can include turning on one or more signals of the GSTV, the NSTV, the toggle, and the like in the display area. The embodiments of the present application do not limit the method of powering on and powering off the display area.

[0226] S913, when the user gazes at the display area a2, the electronic device 100 can power on the display area a2, move the AOD content from the display area a1 to the display area a2, and display the AOD content in the display area a2 while powering off other display areas except the display area a2.

[0227] In some embodiments, the electronic device 100 can capture a face image of the user through the front camera, and detect the gaze direction of the user's eyes according to the captured face image. The electronic device 100 can determine the eye gaze area according to the gaze direction of the user's eyes. For example, if the user's eyes gaze at the display area a2, the electronic device 100 can move the AOD content from the display area a1 to the display area a2. The display area a1 and the display area a2 are at least partially different.

[0228] Optionally, the camera used to detect the gaze direction of the eyes can be a front always-on camera (AOC). In the screen-off display state, the front AOC can work in a low-power mode. The embodiments of the present application do not limit the method of detecting the gaze direction of the eyes. In some embodiments, in the case that the display area a1 and the display area a2 are completely different, the electronic device 100 can power off the display area a1 and power on the display area a2 to display the AOD content in the display area a2. In the case that the display area a1 and the display area a2 partially overlap, the electronic device 100 can power off the display area in the display area a1 that does not overlap with the display area a2, and power on the display area in the display area a2 that does not overlap with the display area a1 to display the AOD content in the display area a2. In this way, the display area of the AOD content can be switched from the display area a1 to the display area a2.

[0229] In some embodiments, the electronic device 100 can display an animation corresponding to the movement of the AOD content from the display area a1 to the display area a2. In this case, the electronic device 100 can power on the display areas that the AOD content needs to pass through during the movement of the AOD content from the display area a1 to the display area a2, in addition to powering on the display area a2. After the animation corresponding to the movement of the AOD content from the display area a1 to the display area a2 is played, the electronic device 100 can power off the display areas that are in the powered-on state except the display area a2. In this case, the electronic device 100 can keep the display areas that do not need to display the AOD content in the powered-off state.

[0230] Alternatively, during the movement of the AOD content from the display area a1 to the display area a2, the electronic device 100 can power on the display areas that need to display the AOD content in the order of the need to display the AOD content, and power off the display areas from which the AOD content moves out. For example, the AOD content moves from the display area a1 to the display area a2 via the display area a4. When the AOD content is displayed in the display area a1, only the display area a1 can be in the powered-on state in the electronic device 100. When the AOD content needs to be displayed in the display area a4, the electronic device 100 can power on the display area a4. When the AOD content is completely moved from the display area a1 to the display area a4, the electronic device 100 can power off the display area a1. Then, when the AOD content needs to be displayed in the display area a2, the electronic device 100 can power on the display area a2. When the AOD content is completely moved from the display area a4 to the display area a2, the electronic device 100 can power off the display area a4. For the display areas other than the display area a1, the display area a2, and the display area a4, the electronic device 100 can keep them in the powered-off state during the movement of the AOD content to the display area a2.

[0231] The timing of powering on or powering off the display areas on the folding screen described above is only an example of the present application and should not be construed as limiting the present application.

[0232] In some embodiments, the electronic device 100 can store an animation file of the AOD. The animation file of the AOD can include the animation in the AOD content moving process described above. When the gaze direction of the human eye changes, the electronic device 100 can read the animation file of the AOD, and display the animation in the AOD content moving process according to the animation file. Alternatively, the animation in the AOD content moving process described above can be generated according to the AOD content stored by the electronic device 100. For example, when the gaze direction of the human eye changes, the electronic device 100 can generate a plurality of images based on the AOD content by using an artificial intelligence (AI) image generation technology, and obtain the animation in the AOD content moving process. Embodiments of the present application do not limit the source of the animation in the AOD content moving process described above.

[0233] The process of moving the AOD content from the display area a1 to the display area a2 described above can refer to the scenario of moving the AOD content from the B screen to the A screen shown in FIG. 4B, and the scenario of moving the AOD content from the A screen to the C screen shown in FIG. 4D.

[0234] For example, when the folding screen is in the fully unfolded state, the display area a1 can be the display area corresponding to the B screen, and the display area a2 can be the display area corresponding to the A screen or the display area corresponding to the C screen. When the AOD content is displayed on the A screen (or the C screen), the B screen and the C screen (or the A screen and the B screen) in the electronic device 100 can be in a powered-off state.

[0235] Alternatively, when the folding screen is in the fully unfolded state, the display area a1 can be the display area corresponding to the A screen and the B screen (for example, the AOD content is displayed at the center position of the display screen composed of the A screen and the B screen), and the display area a2 can be the display area corresponding to the B screen and the C screen (for example, the AOD content is displayed at the center position of the display screen composed of the B screen and the C screen).

[0236] Alternatively, when the folding screen is in the fully unfolded state, the display area a1 is a display area of a part of the B screen, and the display area a2 can be a display area at any position of the display area a1 of the B screen, the A screen, or the C screen. For example, the display area a2 is a part of the display area of the A screen. Alternatively, the display area a2 is composed of a part of the display area of the A screen and a part of the display area of the B screen.

[0237] Alternatively, when the folding screen is in the semi-folded state 1, the display area a1 is the display area corresponding to the B screen and the C screen, and the display area a2 can be the display area corresponding to the B screen or the display area corresponding to the C screen.

[0238] Alternatively, when the folding screen is in the semi-folded state 1, the display area a1 can be composed of a part of the display area on the B screen and a part of the display area on the C screen, and the display area a2 can be a display area at any position on the B screen and the C screen other than the display area a1.

[0239] Alternatively, when the folding screen is in the semi-folded state 2 or the fully unfolded state, the display area a1 can be a part of the display area on the A screen. The display area a2 can be a display area at any position on the A screen other than the display area a1.

[0240] Embodiments of the present application do not limit the positions of the display area a1 and the display area a2 on the folding screen.

[0241] In some embodiments, during the movement of the AOD content from the display area a1 to the display area a2, the electronic device 100 can play corresponding audio to provide a transition sound effect of the AOD movement to the user. Optionally, the electronic device 100 can determine the speaker for playing the audio according to the direction of the AOD movement. For example, the electronic device 100 can include a left speaker and a right speaker. If the AOD content moves left on the display screen, the electronic device 100 can use the left speaker to play the audio during the movement of the AOD content. If the AOD content moves right on the display screen, the electronic device 100 can use the right speaker to play the audio during the movement of the AOD content.

[0242] In some embodiments, if the AOD content moves left on the display screen, the electronic device 100 can use the left speaker and the right speaker to play the audio during the movement of the AOD content, and gradually decrease the loudness of the audio played by the right speaker and gradually increase the loudness of the audio played by the left speaker. Alternatively, if the AOD content moves left on the display screen, the electronic device 100 can first use the right speaker to play the audio during the movement of the AOD content, and gradually transition to using the left speaker to play the audio during the movement of the AOD content. If the AOD content moves right on the display screen, the electronic device 100 can use the left speaker and the right speaker to play the audio during the movement of the AOD content, and gradually decrease the loudness of the audio played by the left speaker and gradually increase the loudness of the audio played by the right speaker. Alternatively, if the AOD content moves right on the display screen, the electronic device 100 can first use the left speaker to play the audio during the movement of the AOD content, and gradually transition to using the right speaker to play the audio during the movement of the AOD content. Embodiments of the present application do not limit the audio during the movement of the AOD content. The audio during the movement of the AOD content can be referred to as AOD transition audio.

[0243] Exemplarily, in the process that the AOD content gradually moves from the C screen to the A screen, the electronic device 100 can play the AOD transition audio using the right speaker when the AOD content is still displayed on the C screen. As the AOD content moves to the left, the electronic device 100 can gradually reduce the loudness of the AOD transition audio played by the right speaker. When the AOD content moves to the B screen, the electronic device 100 can play the AOD transition audio using the left speaker and the right speaker simultaneously. Further, as the AOD content continues to move to the left, the electronic device 100 can gradually increase the loudness of the AOD transition audio played by the left speaker. When the AOD content moves to the A screen, the electronic device 100 can turn off the right speaker and play the AOD transition audio using the left speaker. In this way, the transition sound effect can change with the movement of the AOD content, improving the user experience of using the AOD by the user.

[0244] In the case that the AOD content moves between different display areas on the A screen, the electronic device 100 can play the AOD transition audio using only the left speaker. In the case that the AOD content moves between different display areas on the C screen, the electronic device 100 can play the AOD transition audio using only the right speaker. In the case that the AOD content moves between different display areas on the B screen, the electronic device 100 can play the AOD transition audio using the left speaker and the right speaker simultaneously.

[0245] The embodiments of the present application do not limit the speaker used by the electronic device 100 to play the audio in the process that the AOD content moves.

[0246] S914, the electronic device 100 can receive a click operation acting on the display area a3.

[0247] In some embodiments, the electronic device 100 can detect the click operation acting on the display screen through the touch sensor on the display screen. In the case that the AOD content is displayed on the display area a1, in response to the click operation acting on the display area a3, the electronic device 100 can move the AOD content from the display area a1 to the display area a3. The display area a3 is a different display area from the display area a1.

[0248] Optionally, the device for detecting the click operation can include a touch panel driver integration chip. In the screen-off display state, the touch panel driver integration chip can work in a low-power mode. In the low-power mode, the touch panel driver integration chip can only recognize click operations (e.g., single-click screen operation, double-click screen operation) acting on the display screen, without recognizing other types of operations (e.g., sliding operation) acting on the display screen. Alternatively, in the screen-off display state, the touch panel driver integration chip can also work in a non-low-power mode. In this way, the touch panel driver integration chip can recognize multiple different types of operations acting on the display screen.

[0249] The click operation acting on the display area a3 can be a single-click operation acting on the display area a3. The embodiments of the present application do not limit the user operation acting on the display screen for moving the AOD content.

[0250] In S915, the electronic device 100 can power on the display area a3, move the AOD content from the display area a1 to the display area a3, and display the AOD content on the display area a3, while other display areas except the display area a3 are in the powered-off state.

[0251] The method for moving the AOD content from the display area a1 to the display area a3 by the electronic device 100 can refer to the method for moving the AOD content from the display area a1 to the display area a2 in the aforementioned step S913. Details are not described herein.

[0252] In some embodiments, in the screen-off display state, the electronic device 100 can detect a sliding operation acting on the display screen. The electronic device 100 can determine a trajectory of the AOD content movement according to a trajectory of the sliding operation, so as to realize the movement of the AOD content following the sliding operation. For example, the trajectory of the AOD content movement can be the same as the trajectory of the sliding operation (it should be understood that the two trajectories can be the same within an error range). In this way, in addition to moving the AOD content to the position on the display screen where the display screen is clicked by the user, the user can also perform a sliding operation on the display screen to move the AOD content following the sliding of the finger on the display screen. The above-mentioned embodiments can improve the user experience of the user using the AOD.

[0253] It should be noted that after the AOD content is moved to the display area a2 or the display area a3, if a change in the gaze direction of the human eye is detected, or a click operation acting on another display area is received, the electronic device 100 can move the AOD content again.

[0254] Not limited to the above-mentioned gaze direction of the human eye, the touch operation acting on the display screen, the electronic device 100 can also move the AOD content according to other events for triggering the AOD content movement. For example, the electronic device 100 can also detect the user's air gesture and move the AOD content based on the air gesture. The above-mentioned touch operation acting on the display screen can also be referred to as a touch operation, including but not limited to: click operation, sliding operation, long press operation, etc.

[0255] From the above method, in the screen-off display state, the electronic device 100 can move the AOD content between the plurality of display regions of the display screen according to the change of the gaze direction of the human eye or the change of the touch region. In this way, the interactivity of the AOD content can be improved. And the electronic device 100 can power on the display region where the AOD content is displayed, and power off the display region where the AOD content is not displayed. This not only can reduce the power consumption of the electronic device 100 in the screen-off display state, realize the all-day display of the AOD content on the display screen, but also can reduce the damage of the display screen in the power-on state for a long time. The above-mentioned method can improve the user experience of the user using the AOD.

[0256] In some embodiments, since the display screen used for display can be different when the folding screen is in different folding states, the electronic device 100 can move the AOD content according to the change of the folding state.

[0257] FIGS. 10A-10D exemplarily show some screen-off display scene schematic diagrams.

[0258] In some embodiments, when the folding state of the folding screen changes to any one of the stand states 1-5, the electronic device 100 can power off all the display screens contained in the folding screen. When the folding state of the folding screen changes to any one of the fully unfolded state, the half-folded state 1, the half-folded state 2, and the fully unfolded state, the electronic device 100 can power on the corresponding display screen according to the folding state.

[0259] As shown in FIG. 10A, when the folding screen is in the fully unfolded state, the electronic device 100 can display the AOD content on the B screen. Among them, the B screen is in the power-on state, and the A screen and the C screen are in the power-off state. As the included angle a between the A screen and the B screen decreases, the folding state of the folding screen changes from the fully unfolded to the stand state 2.

[0260] Among them, when the folding state of the folding screen changes to the stand state 2, the electronic device 100 can power off the B screen and keep the A screen and the C screen in the power-off state. That is to say, in the stand state 2, the folding screen of the electronic device 100 is turned off, and the A screen, the B screen and the C screen are all in the power-off state.

[0261] It needs to be explained that if the AOD content is displayed on the A screen in the fully unfolded state, the electronic device 100 can power down the A screen after the folding state of the folding screen changes to the stand state 2, and keep the B screen and the C screen in the powered-on state. That is to say, when the folding state of the folding screen changes from the fully unfolded state to the stand state 2, the electronic device 100 can power down the display area that displays the AOD content in the fully unfolded state, and keep the display area that does not display the AOD content in the fully unfolded state in the powered-off state. The display area that displays the AOD content in the fully unfolded state can be any area on the A screen, the B screen, or the C screen.

[0262] The angle a between the A screen and the B screen continues to decrease. When a decreases to close to 0° or decreases to 0°, the folding state of the folding screen changes from the stand state 2 to the half-folded state 1.

[0263] When the folding state of the folding screen changes to the half-folded state 1, the electronic device 100 can determine the display area for displaying the AOD content according to the half-folded state 1. For details, reference can be made to the foregoing description of step S912 in FIG. 9.

[0264] For example, in the half-folded state 1, the electronic device 100 can determine that the display area for displaying the AOD content is the display area corresponding to the B screen and the C screen. The electronic device 100 can power on the B screen and the C screen, display the AOD content in the central area of the display screen composed of the B screen and the C screen, and keep the A screen in the powered-off state. As shown in FIG. 10A, part of the AOD content (for example, a butterfly image) is displayed on the B screen, and the other part is displayed on the C screen.

[0265] The embodiments of the present application do not limit the display area in which the electronic device 100 displays the AOD content for the first time after the folding state changes to the half-folded state 1. For example, when the folding state of the folding screen changes to the half-folded state 1, the electronic device 100 can determine that the display area for displaying the AOD content is the display area corresponding to the C screen. The electronic device 100 can only power on the C screen, display the AOD content on the C screen, and keep the A screen and the B screen in the powered-off state.

[0266] As can be seen from FIG. 10A, as the folding state of the folding screen changes from the fully unfolded state to the half-folded state 1, the electronic device 100 can change the display position of the AOD content. For example, the display position of the AOD content can change from the center of the B screen to the center of the display screen composed of the B screen and the C screen.

[0267] It can be understood that when α increases, the folding state of the folding screen can change from the half-folded state 1 shown in FIG. 10A to the stand state 2, the electronic device 100 can power off the display area that displays the AOD content in the half-folded state 1, and keep the display area that does not display the AOD content in the half-folded state 1 in the powered-off state. The above-mentioned display area that displays the AOD content in the half-folded state 1 can be any area on the B screen and the C screen. Further, when α continues to increase so that the folding state of the folding screen changes from the stand state 2 to the fully unfolded state, the electronic device 100 can power on the B screen, display the AOD content on the B screen, and keep the A screen and the C screen in the powered-off state. The embodiments of the present application do not limit the display area of the electronic device 100 that first displays the AOD content after the folding state changes to the fully unfolded state.

[0268] As shown in FIG. 10B, when the folding screen is in the fully unfolded state, the electronic device 100 can display the AOD content on the B screen. Among them, the B screen is in the powered-on state, and the A screen and the C screen are in the powered-off state. As the included angle β between the B screen and the C screen decreases, the folding state of the folding screen changes from the fully unfolded state to the stand state 3.

[0269] Among them, when the folding state of the folding screen changes to the stand state 3, the electronic device 100 can power off the B screen, and keep the A screen and the C screen in the powered-off state. That is to say, in the stand state 3, the folding screen of the electronic device 100 is turned off, and the A screen, the B screen and the C screen are all in the powered-off state.

[0270] It should be noted that when the folding state of the folding screen changes from the fully unfolded state to the stand state 3, the electronic device 100 can power off the display area that displays the AOD content in the fully unfolded state, and keep the display area that does not display the AOD content in the fully unfolded state in the powered-off state. The above-mentioned display area that displays the AOD content in the fully unfolded state can be any area on the A screen, the B screen and the C screen.

[0271] The included angle β between the B screen and the C screen continues to decrease. When β decreases to close to 0° or decreases to 0°, the folding state of the folding screen changes from the stand state 3 to the half-folded state 2.

[0272] When the folding state of the folding screen changes to the half-folded state 2, the electronic device 100 can determine the display area for displaying the AOD content according to the half-folded state 2. For details, please refer to the introduction of step S912 in the foregoing FIG. 9.

[0273] For example, in the half-folded state 2, the electronic device 100 can determine that the display area for displaying the AOD content is the display area corresponding to the A screen, the electronic device 100 can power on the A screen, display the AOD content on the A screen, and keep the B screen and the C screen in the powered-off state.

[0274] The embodiments of the present application do not limit the display area of the electronic device 100 for displaying the AOD content for the first time after the folding state of the folding screen changes to the half-folded state 2. For example, when the folding state of the folding screen changes to the half-folded state 2, the electronic device 100 can determine that the display area for displaying the AOD content is the top area of the A screen. The electronic device 100 can only power on the top area of the A screen, display the AOD content on the top area of the A screen, and keep the area of the A screen without displaying the AOD content, the B screen and the C screen in the powered-off state.

[0275] As can be seen from FIG. 10B, as the folding state of the folding screen changes from the fully unfolded state to the half-folded state 2, the electronic device 100 can change the display position of the AOD content. For example, the display position of the AOD content can change from the center of the B screen to the center of the A screen.

[0276] It can be understood that when β increases, the folding state of the folding screen can change from the half-folded state 2 shown in FIG. 10B to the stand state 3, and the electronic device 100 can power off the display area displaying the AOD content in the half-folded state 2 and keep the display area not displaying the AOD content in the half-folded state 2 in the powered-off state. The above-mentioned display area displaying the AOD content in the half-folded state 2 can be any area on the A screen. Further, when β continuously increases and the folding state of the folding screen changes from the stand state 3 to the fully unfolded state, the electronic device 100 powers on the B screen, displays the AOD content on the B screen, and keeps the A screen and the C screen in the powered-off state.

[0277] As shown in FIG. 10C, when the folding screen is in the fully unfolded state, the electronic device 100 can display the AOD content on the B screen. Among them, the B screen is in the powered-on state, and the A screen and the C screen are in the powered-off state. As the angle α between the A screen and the B screen decreases and the angle β between the B screen and the C screen decreases, the folding state of the folding screen changes from the fully unfolded state to the stand state 1.

[0278] Among them, when the folding state of the folding screen changes to the stand state 1, the electronic device 100 can power off the B screen and keep the A screen and the C screen in the powered-off state. That is to say, in the stand state 1, the folding screen of the electronic device 100 is turned off, and the A screen, the B screen and the C screen are all in the powered-off state.

[0279] It should be noted that when the folding state of the folding screen changes from the fully unfolded state to the stand state 1, the electronic device 100 can power off the display area displaying the AOD content in the fully unfolded state and keep the display area not displaying the AOD content in the fully unfolded state in the powered-off state. The above-mentioned display area displaying the AOD content in the fully unfolded state can be any area on the A screen, the B screen or the C screen.

[0280] The angle a and the angle β are continuously reduced. When the angle a and the angle β are reduced to close to 0° or are reduced to 0°, the folding state of the folding screen changes from the support state 1 to a completely folded state.

[0281] When the folding state of the folding screen changes to the completely folded state, the electronic device 100 can determine a display area for displaying AOD content according to the completely folded state. For details, reference can be made to the description of step S912 in the foregoing FIG. 9.

[0282] For example, in the completely folded state, the electronic device 100 can determine the display area for displaying AOD content as the display area corresponding to the A screen, the electronic device 100 can power on the A screen, display AOD content on the A screen, and keep the B screen and the C screen in a powered-off state. The embodiments of the present application do not limit the display area of the electronic device 100 for displaying AOD content for the first time after the folding state changes to the completely folded state.

[0283] As can be seen from FIG. 10C, as the folding state of the folding screen changes from the completely unfolded state to the completely folded state, the electronic device 100 can change the display position of the AOD content. For example, the display position of the AOD content can change from the center of the B screen to the center of the A screen.

[0284] It can be understood that when the angle a and the angle β are increased, the folding state of the folding screen can change from the completely folded state shown in FIG. 10C to the support state 1, the electronic device 100 can power off the display area displaying AOD content in the completely folded state, and keep the display area not displaying AOD content in the completely folded state in a powered-off state. The above-mentioned display area displaying AOD content in the completely folded state can be any area on the A screen. Further, when the angle a and the angle β are continuously increased so that the folding state of the folding screen changes from the support state 1 to the completely unfolded state, the electronic device 100 powers on the B screen, displays AOD content on the B screen, and keeps the A screen and the C screen in a powered-off state.

[0285] As shown in FIG. 10D, when the folding screen is in the half-folded state 1, the electronic device 100 can display AOD content at the center position of the display screen composed of the B screen and the C screen. Among them, the B screen and the C screen are in a powered-on state, and the A screen is in a powered-off state. As the angle β between the B screen and the C screen decreases, the folding state of the folding screen changes from the half-folded state 1 to the support state 4.

[0286] Among them, when the folding state of the folding screen changes to the support state 4, the electronic device 100 can power off the B screen and the C screen, and keep the A screen in a powered-off state. That is to say, in the support state 4, the folding screen of the electronic device 100 is turned off, and the A screen, the B screen and the C screen are all in a powered-off state.

[0287] It should be noted that when the folding state of the folding screen changes from the half-folded state 1 to the stand state 4, the electronic device 100 can power off the display area displaying the AOD content in the half-folded state 1, and keep the display area not displaying the AOD content in the half-folded state 1 in the powered-off state. The display area displaying the AOD content in the half-folded state 1 can be any area on the B screen and the C screen.

[0288] The angle β between the B screen and the C screen continues to decrease. When β decreases to close to 0° or decreases to 0°, the folding state of the folding screen changes from the stand state 4 to the fully folded state.

[0289] When the folding state of the folding screen changes to the fully folded state, the electronic device 100 can determine the display area for displaying the AOD content according to the fully folded state. For details, please refer to the description of step S912 in the foregoing FIG. 9.

[0290] For example, in the fully folded state, the electronic device 100 can determine that the display area for displaying the AOD content is the display area corresponding to the A screen, the electronic device 100 can power on the A screen, display the AOD content on the A screen, and keep the B screen and the C screen in the powered-off state.

[0291] As can be seen from FIG. 10D, as the folding state of the folding screen changes from the half-folded state 1 to the fully folded state, the electronic device 100 can change the display position of the AOD content. For example, the display position of the AOD content can change from the center of the display screen composed of the B screen and the C screen to the center of the A screen.

[0292] It can be understood that when the angle β increases, the folding state of the folding screen can change from the fully folded state shown in FIG. 10D to the stand state 4, the electronic device 100 can power off the display area displaying the AOD content in the fully folded state, and keep the display area not displaying the AOD content in the fully folded state in the powered-off state. The display area displaying the AOD content in the fully folded state can be any area on the A screen. Further, when the angle β continues to increase so that the folding state of the folding screen changes from the stand state 4 to the half-folded state 1, the electronic device 100 can power on the B screen and the C screen, display the AOD content at the center of the display screen composed of the B screen and the C screen, and keep the A screen in the powered-off state.

[0293] From the above scenarios, the display position of the AOD content can change with the change of the folding state. The user can change the display position of the AOD by changing the folding state of the folding screen. In this way, the interactivity of the AOD content can be improved. In addition, in the above scenario of changing the display position of the AOD content according to the change of the folding state, the electronic device 100 can power on the display area that needs to display the AOD content and power off the display area that does not need to display the AOD content. In this way, the power consumption of the electronic device 100 can be reduced.

[0294] FIGS. 11A-11C exemplarily show some scenarios of the screen-off display.

[0295] As shown in FIG. 11A, when the folding screen is in the fully unfolded state, the electronic device 100 can display the AOD content on any area on the A screen, the B screen, and the C screen. The electronic device 100 can power on the display area that displays the AOD content and power off the display area that displays the AOD content. For example, the electronic device can display the AOD content on the B screen. Among them, the B screen is in the powered-on state, and the A screen and the C screen are in the powered-off state. As the included angle a between the A screen and the B screen decreases, the folding state of the folding screen changes from the fully unfolded state to the stand state 2.

[0296] As a gradually decreases, the folding state of the folding screen eventually changes to the half-folded state 1. That is, the stand state 2 is an intermediate state in the process of changing the folding screen from the fully unfolded state to the half-folded state 1. When the folding screen changes from the fully unfolded state to the half-folded state 1, the electronic device 100 can determine the display area for displaying the AOD content according to the half-folded state 1. For details, please refer to the introduction of step S912 in the foregoing FIG. 9. For example, in the half-folded state 1, the electronic device 100 can determine the display area for displaying the AOD content as the display area corresponding to the B screen and the C screen.

[0297] In the process of changing the folding state of the folding screen from the fully unfolded state to the half-folded state 1, the electronic device 100 can move the AOD content from the display area that displays the AOD content in the fully unfolded state to the display area for displaying the AOD content in the half-folded state 1. And the electronic device 100 can display an animation of the movement of the AOD content. Optionally, in the above process of moving the AOD content, the electronic device 100 can play corresponding audio to provide the user with a transition sound effect of the movement of the AOD content.

[0298] In some embodiments, when the folding state of the folding screen starts to change from the fully unfolded state to the half-folded state 1, the electronic device 100 can power on the display area for displaying the AOD content in the half-folded state 1, the display area on which the AOD content moves from the display area displaying the AOD content in the fully unfolded state to the display area for displaying the AOD content in the half-folded state 1, and keep the display area displaying the AOD content in the fully unfolded state in the powered-on state. Further, after the AOD content is completely moved into the display area for displaying the AOD content in the half-folded state 1, the electronic device 100 can power off the display area on which the AOD content is not displayed.

[0299] Alternatively, in the process of moving the AOD content and playing the animation of the movement of the AOD content, the electronic device 100 can power on the display areas in which the AOD content needs to be displayed in sequence according to the order of the display areas in which the AOD content needs to be displayed, and power off the display areas from which the AOD content moves.

[0300] Exemplarily, as shown in FIG. 11A, the folding state of the folding screen changes from the fully unfolded state to the stand state 2, which can represent that the folding state starts to change from the fully unfolded state to the half-folded state 1. When the folding state of the folding screen changes to the stand state 2, the electronic device 100 can determine that the display area for displaying the AOD content in the half-folded state 1 is the central area of the display screen composed of the B screen and the C screen. Therefore, the electronic device 100 can power on the C screen, keep the B screen in the powered-on state, and keep the A screen in the powered-off state.

[0301] In the process of gradually reducing the included angle α, the electronic device 100 can display an animation of the AOD content, for example, a butterfly image, moving from the B screen to the central area of the display screen composed of the B screen and the C screen.

[0302] When the included angle α is reduced to close to 0° or reduced to 0°, the folding state of the folding screen changes to the half-folded state 1, and the AOD content moves to the central area of the display screen composed of the B screen and the C screen. The electronic device 100 can keep the B screen and the C screen in the powered-on state, and keep the A screen in the powered-off state.

[0303] As can be seen from FIG. 11A, in the process of changing the folding state of the folding screen from the fully unfolded state to the half-folded state 1, the user can watch the AOD content gradually moving from the currently displayed position to the central area of the display screen composed of the B screen and the C screen. For example, the AOD content includes a butterfly image. The user can watch the animation of the butterfly flying. Wherein, the butterfly can fly from the B screen to the right to the center of the display screen composed of the B screen and the C screen.

[0304] It can be understood that as the included angle a increases, the folding state of the folding screen can change from the half-folded state 1 to the fully unfolded state. In the process of changing from the half-folded state 1 to the fully unfolded state, the electronic device 100 can move the AOD content from the display area displaying the AOD content in the half-folded state 1 to the display area for displaying the AOD content in the fully unfolded state. Moreover, the electronic device 100 can display an animation of the movement of the AOD content. The timing of the electronic device 100 powering on or powering off the display area of the folding screen in the process of moving the AOD content can refer to the foregoing introduction of powering on or powering off the display area in the process of changing from the fully unfolded state to the half-folded state 1.

[0305] For example, when the folding state of the folding screen changes from the half-folded state 1 to the stand state 2, the electronic device 100 can keep the B screen and the C screen in the powered-on state, and move the AOD content from the center area of the display screen composed of the B screen and the C screen to the center area of the B screen. When the folding state of the folding screen changes from the stand state 2 to the fully unfolded state, the electronic device 100 can power off the C screen, keep the B screen in the powered-on state, and keep the A screen in the powered-off state. The electronic device 100 can display the AOD content in the center area of the B screen. In this way, the user can watch the AOD content gradually moving from the center area of the display screen composed of the B screen and the C screen to the center area of the B screen. For example, the AOD content includes a butterfly image. The user can watch the animation of the butterfly flying. Wherein, the butterfly can fly from the center of the display screen composed of the B screen and the C screen to the center of the B screen to the left.

[0306] As shown in FIG. 11B, the folding screen is in the fully unfolded state. The electronic device 100 can display the AOD content on the B screen. Wherein, the B screen is in the powered-on state, and the A screen and the C screen are in the powered-off state. When the folding screen is in the fully unfolded state, the electronic device 100 can display the AOD content in any area of the A screen, the B screen, and the C screen, not limited to the B screen. As the included angle β between the B screen and the C screen decreases, the folding state of the folding screen changes from the fully unfolded state to the stand state 3.

[0307] As β gradually decreases, the folding state of the folding screen eventually changes to the half-folded state 2. That is, the stand state 3 is an intermediate state in the process of changing from the fully unfolded state to the half-folded state 2 of the folding screen. When the folding screen changes from the fully unfolded state to the half-folded state 2, the electronic device 100 can determine the display area for displaying the AOD content according to the half-folded state 2. For details, please refer to the foregoing introduction of step S912 in FIG. 9. For example, in the half-folded state 2, the electronic device 100 can determine the display area for displaying the AOD content as the display area corresponding to the A screen.

[0308] In a process that the folding state of the folding screen changes from the fully unfolded state to the half-folded state 2, the electronic device 100 can move the AOD content from the display area displaying the AOD content in the fully unfolded state to the display area for displaying the AOD content in the half-folded state 2. And the electronic device 100 can display an animation of the AOD content moving. Optionally, in the process of the AOD content moving, the electronic device 100 can play corresponding audio to provide the user with a transition sound effect of the AOD content moving.

[0309] In some embodiments, when the folding state of the folding screen starts to change from the fully unfolded state to the half-folded state 2, the electronic device 100 can power on the display area for displaying the AOD content in the half-folded state 2, and the display area that the AOD content needs to move from the display area displaying the AOD content in the fully unfolded state to the display area for displaying the AOD content in the half-folded state 2, and keep the display area displaying the AOD content in the fully unfolded state in the powered-on state. Further, after the AOD content is completely moved into the display area for displaying the AOD content in the half-folded state 2, the electronic device 100 can power off the display area that does not display the AOD content.

[0310] Alternatively, in the process of moving the AOD content and playing the animation of the AOD content moving, the electronic device 100 can power on the display areas that need to display the AOD content in sequence according to the order of the AOD content, and power off the display areas that the AOD content moves out of.

[0311] Exemplarily, as shown in FIG. 11B, the folding state of the folding screen changes from the fully unfolded state to the stand state 3, which can represent that the folding state starts to change from the fully unfolded state to the half-folded state 2. When the folding state of the folding screen changes to the stand state 3, the electronic device 100 can determine that the display area for displaying the AOD content in the half-folded state 2 is the display area corresponding to the A screen. Therefore, the electronic device 100 can power on the A screen, keep the B screen in the powered-on state, and keep the B screen in the powered-off state.

[0312] In the process that the included angle β gradually decreases, the electronic device 100 can display an animation of the AOD content, such as a butterfly image, moving from the B screen to the A screen.

[0313] When the included angle β decreases to close to 0° or decreases to 0°, the folding state of the folding screen changes to the half-folded state 2, and the AOD content moves to the A screen. The electronic device 100 can keep the A screen in the powered-on state, power off the B screen, and keep the C screen in the powered-off state.

[0314] As can be seen from FIG. 11B, in the process that the folding state of the folding screen changes from the fully unfolded state to the half-folded state 2, the user can watch the AOD content gradually move from the currently displayed position to the A screen. For example, the AOD content includes a butterfly image. The user can watch the animation of the butterfly flying. Wherein, the butterfly can fly from the B screen to the left to the A screen.

[0315] It can be understood that when the included angle β increases, the folding state of the folding screen can change from the half-folded state 2 to the fully unfolded state. In the process of changing from the half-folded state 2 to the fully unfolded state, the electronic device 100 can move the AOD content from the display area displaying the AOD content in the half-folded state 2 to the display area for displaying the AOD content in the fully unfolded state. And the electronic device 100 can display the animation of the AOD content moving. The timing of the electronic device 100 powering on or powering off the display area of the folding screen during the movement of the AOD content can refer to the foregoing introduction of powering on or powering off the display area in the process of changing from the fully unfolded state to the half-folded state 2.

[0316] For example, when the folding state of the folding screen changes from the half-folded state 2 to the stand state 3, the electronic device 100 can power on the B screen, keep the A screen in the powered-on state, and move the AOD content from the A screen to the B screen. When the folding state of the folding screen changes from the stand state 3 to the fully unfolded state, the electronic device 100 can power off the A screen, keep the B screen in the powered-on state, and keep the C screen in the powered-off state. The electronic device 100 can display the AOD content on the center area of the B screen. In this way, the user can watch the AOD content gradually move from the A screen to the B screen. For example, the AOD content includes a butterfly image. The user can watch the animation of the butterfly flying. Wherein, the butterfly can fly from the A screen to the right to the B screen.

[0317] As shown in FIG. 11C, the folding screen is in the fully unfolded state. The electronic device 100 can display the AOD content on the C screen. Wherein, the C screen is in the powered-on state. The A screen and the B screen are in the powered-off state. When the folding screen is in the fully unfolded state, the electronic device 100 can display the AOD content on any area of the A screen, the B screen, and the C screen. As the included angle α between the A screen and the B screen and the included angle β between the B screen and the C screen decrease, the folding state of the folding screen changes from the fully unfolded state to the stand state 1.

[0318] As a and b gradually decrease, the folding state of the folding screen eventually changes to a fully folded state. That is, the support state 1 is an intermediate state in the process of the folding screen changing from a fully unfolded state to a fully folded state. When the folding screen changes from a fully unfolded state to a fully folded state, the electronic device 100 can determine the display area for displaying the AOD content according to the fully folded state. For details, reference can be made to the description of step S912 in the foregoing FIG. 9. For example, in the fully folded state, the electronic device 100 can determine the display area for displaying the AOD content as the display area corresponding to the A screen.

[0319] In the process of the folding state of the folding screen changing from a fully unfolded state to a fully folded state, the electronic device 100 can move the AOD content from the display area displaying the AOD content in the fully unfolded state to the display area for displaying the AOD content in the fully folded state. In addition, the electronic device 100 can display an animation of the movement of the AOD content. Optionally, in the process of the movement of the AOD content, the electronic device 100 can play corresponding audio to provide a transition sound effect of the movement of the AOD content to the user.

[0320] In some embodiments, when the folding state of the folding screen starts to change from a fully unfolded state to a fully folded state, the electronic device 100 can power on the display area for displaying the AOD content in the fully folded state and the display area through which the AOD content needs to move from the display area displaying the AOD content in the fully unfolded state to the display area for displaying the AOD content in the fully folded state, and keep the display area displaying the AOD content in the fully unfolded state in a powered-on state. Further, after the AOD content is completely moved into the display area for displaying the AOD content in the fully folded state, the electronic device 100 can power off the display area not displaying the AOD content.

[0321] Alternatively, in the process of moving the AOD content and playing the animation of the movement of the AOD content, the electronic device 100 can power on the display areas in which the AOD content needs to be displayed in sequence according to the order of the need to display the AOD content, and power off the display areas from which the AOD content is moved.

[0322] Exemplarily, as shown in FIG. 11C, the folding state of the folding screen changes from a fully unfolded state to a support state 1, which can represent that the folding state starts to change from a fully unfolded state to a fully folded state. When the folding state of the folding screen changes to the support state 1, the electronic device 100 can determine that the display area for displaying the AOD content in the fully folded state is the display area corresponding to the A screen. Therefore, the electronic device 100 can power on the A screen and the B screen, and keep the C screen in a powered-on state. The B screen is the display area through which the AOD content needs to be moved from the C screen to the A screen.

[0323] In the process of gradually reducing the included angle a and the included angle b, the electronic device 100 can display the AOD content, for example, the butterfly image, moving from the C screen to the A screen.

[0324] When the included angle a and the included angle b are reduced to close to 0° or reduced to 0°, the folding state of the folding screen changes to the fully folded state, and the AOD content moves to the A screen. The electronic device 100 can keep the A screen in the powered-on state and power off the B screen and the C screen.

[0325] As can be seen from FIG. 11C, in the process of changing the folding state of the folding screen from the fully unfolded state to the fully folded state, the user can watch the AOD content gradually moving from the currently displayed position to the A screen. For example, the AOD content includes a butterfly image. The user can watch the animation of the butterfly flying. Wherein, the butterfly can fly from the C screen to the left, pass through the B screen, and fly to the A screen.

[0326] It can be understood that when the included angle a and the included angle b are both increased, the folding state of the folding screen can change from the fully folded state to the fully unfolded state. In the process of changing from the fully folded state to the fully unfolded state, the electronic device 100 can move the AOD content from the display area displaying the AOD content in the fully folded state to the display area for displaying the AOD content in the fully unfolded state. And the electronic device 100 can display the animation of the AOD content moving. The timing of the electronic device 100 powering on or powering off the display area of the folding screen in the process of moving the AOD content can refer to the foregoing introduction of powering on or powering off the display area in the process of changing from the fully unfolded state to the fully folded state.

[0327] For example, when the folding state of the folding screen changes from the fully folded state to the stand state 1, the electronic device 100 can power on the B screen, keep the A screen in the powered-on state, and move the AOD content from the A screen to the B screen. When the folding state of the folding screen changes from the stand state 1 to the fully unfolded state, the electronic device 100 can power off the A screen, keep the B screen in the powered-on state, and keep the C screen in the powered-off state. The electronic device 100 can display the AOD content on the center area of the B screen. In this way, the user can watch the AOD content gradually moving from the A screen to the B screen. For example, the AOD content includes a butterfly image. The user can watch the animation of the butterfly flying. Wherein, the butterfly can fly from the A screen to the right to the B screen.

[0328] In the process of changing the folding state from the half-folded state 1 to the fully folded state, or from the fully folded state to the half-folded state 1, or from the half-folded state 2 to the fully folded state, or from the fully folded state to the half-folded state 2, or from the half-folded state 1 to the half-folded state 2, or from the half-folded state 2 to the half-folded state 1, the method of the electronic device 100 moving the AOD content display position can refer to the foregoing introduction of FIGS. 11A-11C. Here, it will not be described again.

[0329] From the above scenario, the display position of the AOD content can change with the change of the folding state. And in the process of changing the folding state, the electronic device 100 can display an animation of the AOD content moving in the corresponding display area. The user can intuitively see the process of the AOD content moving when changing the folding state of the folding screen. This can improve the interactivity of the AOD content. In addition, in the above scenario of changing the display position of the AOD content according to the change of the folding state, the electronic device 100 can power on the display area where the AOD content needs to be displayed, and power off the display area where the AOD content does not need to be displayed. In this way, the power consumption of the electronic device 100 can be reduced.

[0330] FIG. 12 exemplarily shows a flowchart of a screen-off display method provided by the present application.

[0331] S1211, the electronic device 100 can display the AOD content in the display area b1, and the display areas other than the display area b1 are in a powered-off state, and the folding screen is in a folding state 1.

[0332] The display area b1 can be any area for displaying the AOD content when the folding screen is in the folding state 1.

[0333] The folding state 1 can be one of a fully unfolded state, a half-folded state 1, a half-folded state 2, and a fully folded state.

[0334] For example, if the folding state 1 is the fully unfolded state, the display area b1 can be any area on the A screen, the B screen, or the C screen.

[0335] If the folding state 1 is the half-folded state 1, the display area b1 can be any area on the B screen and the C screen.

[0336] If the folding state 1 is the half-folded state 2 or the fully folded state, the display area b1 can be any area on the A screen.

[0337] The size of the display area b1 is not limited in the embodiments of the present application. For example, the size of the display area b1 can be the same as the size of the A screen or the B screen or the C screen. Alternatively, the size of the display area b1 can be smaller than the size of the A screen or the B screen or the C screen.

[0338] S1212, the electronic device 100 detects that the folding state of the folding screen changes to a folding state 2, and determines that the display area for performing screen-off display according to the folding state 2 is a display area b2.

[0339] The folding state 2 can be one of a fully unfolded state, a half-folded state 1, a half-folded state 2, and a fully folded state. The folding state 2 is different from the folding state 1.

[0340] For example, if the folding state 2 is the fully unfolded state, the display area b2 can be any area on the A screen, the B screen, or the C screen.

[0341] If the folding state 2 is the half-folded state 1, the display area b2 can be any area on the B screen and the C screen.

[0342] If the folding state 2 is the half-folded state 2 or the fully folded state, the display area b2 can be any area on the A screen.

[0343] Embodiments of the present application do not limit the size of the display area b2. For example, the size of the display area b2 can be the same as the size of the A screen or the B screen or the C screen. Alternatively, the size of the display area b2 can be smaller than the size of the A screen or the B screen or the C screen.

[0344] In some embodiments, in a case where the folding state 1 is the fully unfolded state, if the included angle a between the A screen and the B screen decreases, the electronic device 100 can determine that the folding state of the folding screen changes from the fully unfolded state to the half-folded state 1 (i.e., the folding state 2 is the half-folded state 1). In a case where the folding state 1 is the fully unfolded state, if the included angle b between the B screen and the C screen decreases, the electronic device 100 can determine that the folding state of the folding screen changes from the fully unfolded state to the half-folded state 2 (i.e., the folding state 2 is the half-folded state 2). In a case where the folding state 1 is the fully unfolded state, if both the included angle a and the included angle b decrease, the electronic device 100 can determine that the folding state of the folding screen changes from the fully unfolded state to the fully folded state (i.e., the folding state 2 is the fully folded state).

[0345] In a case where the folding state 1 is the half-folded state 1, if the included angle a increases, the electronic device 100 can determine that the folding state of the folding screen changes from the half-folded state 1 to the fully unfolded state (i.e., the folding state 2 is the fully unfolded state). In a case where the folding state 1 is the half-folded state 1, if the included angle b decreases, the electronic device 100 can determine that the folding state of the folding screen changes from the half-folded state 1 to the fully folded state (i.e., the folding state 2 is the fully folded state). In a case where the folding state 1 is the half-folded state 1, if the included angle a increases and the included angle b decreases, the electronic device 100 can determine that the folding state of the folding screen changes from the half-folded state 1 to the half-folded state 2 (i.e., the folding state 2 is the half-folded state 2).

[0346] In a case where the folding state 1 is the half-folded state 2, if the included angle β increases, the electronic device 100 can determine that the folding state of the folding screen changes from the half-folded state 2 to the fully unfolded state (i.e., the folding state 2 is the fully unfolded state). In a case where the folding state 1 is the half-folded state 2, if the included angle α decreases, the electronic device 100 can determine that the folding state of the folding screen changes from the half-folded state 2 to the fully folded state (i.e., the folding state 2 is the fully folded state). In a case where the folding state 1 is the half-folded state 2, if the included angle α decreases and the included angle β increases, the electronic device 100 can determine that the folding state of the folding screen changes from the half-folded state 2 to the half-folded state 1 (i.e., the folding state 2 is the half-folded state 1).

[0347] In a case where the folding state 1 is the fully folded state, if both the included angle α and the included angle β increase, the electronic device 100 can determine that the folding state of the folding screen changes from the fully folded state to the fully unfolded state (i.e., the folding state 2 is the fully unfolded state). In a case where the folding state 1 is the fully folded state, if the included angle β increases, the electronic device 100 can determine that the folding state of the folding screen changes from the fully folded state to the half-folded state 1 (i.e., the folding state 2 is the half-folded state 1). In a case where the folding state 1 is the fully folded state, if the included angle α increases, the electronic device 100 can determine that the folding state of the folding screen changes from the fully folded state to the half-folded state 2 (i.e., the folding state 2 is the half-folded state 2).

[0348] S1213, the electronic device 100 can power on the display area b2, move the AOD content from the display area b1 to the display area b2, and keep other display areas in a powered-off state when the display area b2 displays the AOD content.

[0349] In the process of changing the folding state of the folding screen from the folding state 1 to the folding state 2, one of the support states 1 to 5 can be passed through.

[0350] In some embodiments, when the folding state of the folding screen changes to any one of the support states 1 to 5, the electronic device 100 can power off all display areas of the folding screen (including keeping the display areas already in the powered-off state in the powered-off state). When the folding state of the folding screen changes to the folding state 2, the electronic device 100 can power on the display area b2, display the AOD content on the display area b2, and keep other display areas in a powered-off state. For details, refer to the foregoing descriptions of the scenarios shown in FIGS. 10A to 10D.

[0351] In some embodiments, when the folding state of the folding screen is detected to change from folding state 1 to folding state 2, the electronic device 100 can power on the display area b2, the display area on which the AOD content needs to pass to move from the display area b1 to the display area b2, and keep the display area b1 in the powered-on state. The electronic device 100 can display an animation of the AOD content moving from the display area b1 to the display area b2. After the above-mentioned animation is played, the electronic device 100 powers off the display areas in the powered-on state except the display area b2. Among them, the electronic device 100 can keep the display areas in which the AOD content is not displayed in the powered-off state. For details, please refer to the introduction of the above-mentioned scenarios shown in FIGS. 11A-11C.

[0352] Alternatively, in the process of moving the AOD content from the display area b1 to the display area b2, the electronic device 100 can power on the display areas in which the AOD content needs to be displayed in the order of the AOD content in sequence, and power off the display areas from which the AOD content moves out. For example, the AOD content moves from the display area b1 to the display area b2 through the display area b3. When the AOD content is completely displayed in the display area b1, only the display area b1 in the electronic device 100 can be in the powered-on state. When the AOD content needs to be displayed in the display area b3, the electronic device 100 can power on the display area b3. When the AOD content is completely moved from the display area b1 to the display area b3, the electronic device 100 can power off the display area b1. Then, when the AOD content needs to be displayed in the display area b2, the electronic device 100 can power on the display area b2. When the AOD content is completely moved from the display area b3 to the display area b2, the electronic device 100 can power off the display area b3. For other display areas except the display area b1, the display area b2, and the display area b3, the electronic device 100 can always keep them in the powered-off state in the process of moving the AOD content to the display area b2.

[0353] As can be seen from the above method, the electronic device 100 can move the AOD content according to the change of the folding state. And in the process of changing the folding state, the electronic device 100 can display an animation of the AOD content moving in the corresponding display area. The user can intuitively see the process of the AOD content moving when changing the folding state of the folding screen. This can improve the interactivity of the AOD content. In addition, in the above-mentioned scenario of changing the display position of the AOD content according to the change of the folding state, the electronic device 100 can power on the display areas in which the AOD content needs to be displayed, and power off the display areas in which the AOD content does not need to be displayed. This not only can reduce the power consumption of the electronic device 100, but also can reduce the damage of the display screen in the long time powered-on state.

[0354] In some embodiments, the electronic device 100 can detect whether the AOD follow-up feature identifier exists when the electronic device 100 is powered on for the first time. The AOD follow-up feature identifier can be used to indicate that the electronic device 100 supports moving the AOD content to any display area on the display screen according to the event for triggering the AOD content movement in the screen-off display state. If the AOD follow-up feature identifier exists in the electronic device 100, the electronic device 100 can configure the related parameters for controlling the AOD content movement, and provide a switch for turning on / off the AOD follow-up feature. In this way, the user can turn on / off the AOD follow-up feature as needed.

[0355] FIG. 13 illustrates a flowchart of a screen-off display method provided by the present application.

[0356] S1311, the electronic device 100 receives a power-on operation.

[0357] The power-on operation can be the first power-on operation after the electronic device 100 is factory-finished. For example, the power-on operation can be the operation of pressing the power key for a long time.

[0358] The electronic device 100 can provide a first power-on navigation for the user to set the information such as the language to be used, the user name, the device unlocking password, and the like when the electronic device 100 is powered on for the first time.

[0359] In some embodiments, in response to the power-on operation, the electronic device 100 can determine the folding state of the folding screen by using the magnetic sensor, and then determine the display screen for displaying the user interface (for example, the power-on navigation interface) after the electronic device 100 is powered on. The method for determining the folding state by using the magnetic sensor can refer to the description of the aforementioned step S912 shown in FIG. 9.

[0360] For example, if the folding screen is in the fully unfolded state, the electronic device 100 can regard the A screen, the B screen, and the C screen as one complete display screen, and display the user interface after the electronic device 100 is powered on on the display screen composed of the A screen, the B screen, and the C screen.

[0361] If the folding screen is in the half-folded state 1, the electronic device 100 can regard the B screen and the C screen as one complete display screen, and display the user interface after the electronic device 100 is powered on on the display screen composed of the B screen and the C screen. The A screen can be in the powered-off state.

[0362] If the folding screen is in the half-folded state 2 or the fully folded state, the electronic device 100 can display the user interface after the electronic device 100 is powered on on the A screen. The B screen and the C screen can be in the powered-off state.

[0363] S1312, when the AOD follow-up feature identifier exists, the electronic device 100 can configure the partition power-off feature parameter, and the partition power-off parameter includes the instructions for powering on / off the multiple display areas respectively.

[0364] In the process of first booting, the electronic device 100 can detect whether there is an AOD follow-up feature identifier. If the electronic device 100 supports moving AOD content to any display area on the display screen according to an event for triggering AOD content movement in the screen-off display state, the electronic device 100 can write the AOD follow-up feature identifier in the memory before leaving the factory. The value of the AOD follow-up feature identifier is not limited in the embodiments of the present application.

[0365] When the AOD follow-up feature identifier exists in the electronic device 100, the electronic device 100 can configure related parameters for controlling AOD content movement, for example, partition power-off feature parameters. The electronic device 100 can use the partition power-off feature parameters to power on the display area where AOD content needs to be displayed, and power off the display area where AOD content does not need to be displayed.

[0366] The related parameters for controlling AOD content movement can also include information of display areas for displaying AOD content in different folding states, etc.

[0367] The electronic device 100 configuring the related parameters for controlling AOD content movement can include loading the related parameters for controlling AOD content movement to the memory. In this way, the AOD application in the electronic device 100 can read the power-on / power-off instructions from the memory to control the display screen partition power-off.

[0368] S1313, the electronic device 100 can provide a switch for turning on or off the AOD follow-up feature.

[0369] When the AOD follow-up feature identifier exists in the electronic device 100, the electronic device 100 can provide a switch for turning on or off the AOD follow-up feature in the process of first booting navigation. In this way, the user can turn on or off the AOD follow-up feature when the electronic device 100 is first booted.

[0370] The electronic device 100 can also provide a switch for turning on or off the AOD follow-up feature in the user interface of the settings application. After the end of the first booting navigation, the user can find the switch for turning on or off the AOD follow-up feature in the user interface of the settings application, so as to turn on or off the AOD follow-up feature.

[0371] In some embodiments, the electronic device 100 can store a mode flag of the AOD follow-up feature. The mode flag can indicate whether the AOD follow-up feature is enabled. If the user does not set the switch state of the AOD follow-up feature (for example, the user skips the stage of setting the switch state of the AOD follow-up feature during the first boot navigation), the mode flag can be empty. If the user enables the AOD follow-up feature, the electronic device 100 can assign a value to the mode flag. The value of the mode flag can be the value corresponding to the enabled AOD follow-up feature, for example, the value is 1. If the user disables the AOD follow-up feature, the electronic device 100 can assign a value to the mode flag. The value of the mode flag can be the value corresponding to the disabled AOD follow-up feature, for example, the value is -1. The value of the mode flag is only an example of the present application, and should not constitute a limitation on the present application.

[0372] The electronic device 100 can determine whether the AOD follow-up feature is enabled according to the mode flag of the AOD follow-up feature.

[0373] S1314, when the AOD follow-up feature is enabled, the electronic device 100 can move the display of the AOD content according to one or more of the folding state change of the folding screen, the change of the gaze direction of the human eye, and the display area affected by the touch operation after the screen is turned off.

[0374] In the case where the AOD follow-up feature is enabled, the scenarios in which the electronic device 100 moves the display of the AOD content can refer to the descriptions of FIGS. 4A-4E, 5A-5C, 6A-6E, 7A-7C, 8A-8E, 10A-10D, 11A-11C.

[0375] S1315, when the AOD follow-up feature is disabled, the electronic device 100 can display the AOD content in a preset display area after the screen is turned off, and power down other display areas other than the preset display area.

[0376] In the case where the AOD follow-up feature is disabled, the electronic device 100 can not need to detect events for triggering the movement of the AOD content, so as not to move the AOD content.

[0377] It needs to be noted that in the case of non-first boot, the electronic device 100 can not need to perform the above step S1312. After the electronic device 100 is booted, the electronic device 100 can read the parameters for controlling the movement of the AOD content configured during the first boot, and provide the function of the AOD follow-up feature for the user by using the above parameters.

[0378] From the above method, the electronic device 100 can configure the related parameters for controlling the movement of the AOD content at the first boot, to support the AOD follow-up feature. In this way, in the case that the AOD follow-up feature is turned on, the electronic device 100 can move the AOD content in any display area of the display screen according to the event for triggering the movement of the AOD content, thereby improving the interactivity of the AOD content.

[0379] FIG. 14 exemplarily shows a scenario of turning on / off the AOD follow-up feature provided in the present application.

[0380] As shown in FIG. 14, the electronic device 100 can display a user interface 1410. The user interface 1410 can include a switch 1411, prompt information 1412.

[0381] The switch 1411 can be used to turn on or turn off the AOD follow-up feature. The switch 1411 is in the on state shown in FIG. 14, which can indicate that the electronic device 100 currently turns on the AOD follow-up feature. When the switch 1411 is in the on state, in response to the operation of the switch 1411, such as a click operation, the electronic device 100 can change the state of the switch 1411 to the off state and turn off the AOD follow-up feature. The embodiments of the present application do not limit the on state and the off state of the switch 1411.

[0382] The prompt information 1412 can be used to prompt the user of the use method of the AOD follow-up feature. For example, the prompt information 1412 can prompt the user to move the AOD content by changing the gaze direction of the human eye or touching the display screen. The embodiments of the present application do not limit the specific content of the prompt information 1412.

[0383] From the above scenario, the user can turn on or turn off the AOD follow-up feature as needed.

[0384] In some embodiments, the electronic device 100 can be connected to an extended display screen. The electronic device 100 can move the AOD content to the extended display screen.

[0385] FIG. 15 shows a schematic diagram of a communication system provided in the present application.

[0386] As shown in FIG. 15, the communication system can include an electronic device 100 and one or more extended display screens. The electronic device 100 can be configured with one display screen or multiple display screens, such as display screen 1, display screen 2, and the like. The display screen 1 and the display screen 2 can be the display screens provided by the electronic device 100. The display screens provided by the electronic device 100 can be configured with the processor, the audio output device, and the like of the electronic device 100 in a separate and complete device. For example, the A screen, the B screen, and the C screen shown in the foregoing FIG. 1A can be the display screens provided by the electronic device 100.

[0387] The electronic device 100 can establish a communication connection with one or more extended display screens. For example, the extended display screens connected by the electronic device 100 can include an extended display screen 1, an extended display screen 2, and the like. The embodiments of the present application do not limit the method of establishing a communication connection between the electronic device 100 and the extended display screen.

[0388] In some embodiments, the electronic device 100 establishes a communication connection with other devices having display screens. The electronic device 100 can serve as a master device and take the display screens of the devices having a communication connection with the electronic device 100 as extended display screens. The electronic device 100 can control the display content on the extended display screens. For example, a mobile phone can be connected with a tablet computer. The display screen of the tablet computer can serve as an extended display screen of the mobile phone.

[0389] The electronic device 100 can move the AOD content on any area of the display screen of the electronic device 100 and the extended display screen according to the event for triggering the movement of the AOD content.

[0390] FIG. 16 exemplarily shows a flowchart of an off-screen display method provided by the present application.

[0391] S1611, the electronic device 100 detects an off-screen event, and the electronic device 100 includes k display screens, which include the display screen of the electronic device 100 and / or the extended display screen.

[0392] k is a positive integer.

[0393] For example, the k display screens include the A screen, the B screen, and the C screen shown in FIG. 1A. The k display screens also include one or more extended display screens controlled by the electronic device 100 to display.

[0394] S1612, the electronic device 100 displays AOD content on a display screen 1 in the k display screens according to a preset AOD theme, and when the display screen 1 displays the AOD content, the other display screens except the display screen 1 are in a powered-off state.

[0395] The display screen 1 can be any one of the k display screens.

[0396] S1613, when the user gazes at a display screen 2, the electronic device 100 powers on the display screen 2 and moves the AOD content from the display screen 1 to the display screen 2, and when the display screen 2 displays the AOD content, the other display screens except the display screen 2 are in a powered-off state.

[0397] The display screen 2 can be any one of the k display screens, and the display screen 1 is different from the display screen 2.

[0398] In some embodiments, the electronic device 100 can capture an image through a camera in the electronic device 100, for example, the front camera arranged on the A screen as shown in FIG. 1A. Alternatively, the electronic device 100 is in communication connection with an image capturing device. The electronic device 100 can obtain an image captured by the image capturing device. The electronic device 100 can determine the gaze direction of the human eye according to the image. The embodiments of the present application do not limit the image capturing device for determining the gaze direction of the human eye.

[0399] When detecting that the human eye gazes at the display screen 2, the electronic device 100 can move the AOD content from the display screen 1 to the display screen 2.

[0400] In some embodiments, the electronic device 100 can display an animation corresponding to the movement of the AOD content from the display screen 1 to the display screen 2. In this case, the electronic device 100 can power on the display screen 2 and the display screens that the AOD content needs to pass through during the movement of the AOD content from the display screen 1 to the display screen 2. After the animation corresponding to the movement of the AOD content from the display screen 1 to the display screen 2 is played, the electronic device 100 can power off the display screens that are in the powered-on state except the display screen 2. In this case, the electronic device 100 can keep the display screens that do not need to display the AOD content in the powered-off state.

[0401] Alternatively, during the movement of the AOD content from the display screen 1 to the display screen 2, the electronic device 100 can power on the display screens in the order of the need to display the AOD content, and power off the display screens from which the AOD content moves out.

[0402] S1614, the electronic device 100 receives a click operation acting on the display screen 3.

[0403] The display screen 3 can be any one of the k display screens. The display screen 3 is different from the display screen 1.

[0404] In some embodiments, the display screen 3 can be provided with a touch sensor. The electronic device 100 can detect the click operation acting on the display screen 3 through the touch sensor on the display screen 3.

[0405] In the case that the AOD content is displayed on the display screen 1, in response to the click operation acting on the display screen 3, the electronic device 100 can move the AOD content from the display screen 1 to the display screen 3.

[0406] S1615, the electronic device 100 powers on the display screen 3, moves the AOD content from the display screen 1 to the display screen 3, and when the display screen 3 displays the AOD content, the other display screens except the display screen 3 are in the powered-off state.

[0407] The method that the electronic device 100 moves the AOD content from the display screen 1 to the display screen 3 can refer to the method that the AOD content is moved from the display screen 1 to the display screen 2 in the foregoing step S1613. Details are not repeated here.

[0408] In some embodiments, the electronic device 100 can detect whether the k display screens support partition power down. That one display screen supports partition power down can mean that, in the case that one part of the display screen is in the power-on state, another part of the display screen can be in the power-down state. The AOD content can only occupy a part of the display area of the display screen. If the k display screens support partition power down, the electronic device 100 can power on the display area of the display screen on which the AOD content is displayed, and power down the other display area on which the AOD content is not displayed. In this way, the power consumption of the electronic device 100 in the screen-off display state can be better reduced, and the damage of the display screen caused by being in the power-on state for a long time can be reduced.

[0409] For example, the display screen 1 supports partition power down. In the foregoing step S1612, in addition to powering down the other display screens except the display screen 1, the electronic device 100 can also power down the display area of the display screen 1 on which the AOD content is not displayed. That is, the electronic device 100 can only power on the display area of the display screen 1 on which the AOD content is displayed.

[0410] The display screen 2 supports partition power down. In the foregoing step S1613, the electronic device 100 powers on the display screen 2, specifically, powers on the part of the display area of the display screen 2 on which the AOD content needs to be displayed. When the part of the display area of the display screen 2 displays the AOD content, the display area of the display screen 2 on which the AOD content is not displayed, and the other display screens except the display screen 2 can all be in the power-down state.

[0411] The display screen 3 supports partition power down. In the foregoing step S1615, the electronic device 100 powers on the display screen 3, specifically, powers on the part of the display area of the display screen 3 on which the AOD content needs to be displayed. When the part of the display area of the display screen 3 displays the AOD content, the display area of the display screen 3 on which the AOD content is not displayed, and the other display screens except the display screen 3 can all be in the power-down state.

[0412] The electronic device 100 can move the AOD content between different display areas of one display screen according to the event for triggering the AOD content movement. In this way, the accuracy of the position movement of the AOD content can be improved, and the interactivity between the user and the AOD content can be better improved.

[0413] Not limited to moving the AOD content on the k display screens according to the gaze area of the human eye and / or the touch operation of the user on the display screen, the electronic device 100 can also move the AOD content according to other rules. For example, the electronic device 100 can move the AOD content from the currently displayed display screen to the adjacent display screen every preset time length. After the AOD content is moved, the display area displaying the AOD content can be in the powered-on state, and the display area not displaying the AOD content can be in the powered-off state. Optionally, during the above-mentioned movement of the AOD content, the electronic device 100 can display an animation of the movement of the AOD content and play corresponding audio to provide the user with a transition sound effect of the movement of the AOD content. The present application embodiment does not limit the rules for triggering the movement of the AOD content. The above-mentioned embodiments can not only improve the interactivity between the user and the AOD content, but also reduce the power consumption of the electronic device 100 in the screen-off display state and reduce the damage of the display screen in the powered-on state for a long time.

[0414] In some embodiments, the electronic device 100 can format data in the electronic device 100. When formatting, the clear data of the electronic device 100 can include the mode flag bit of the AOD follow-up feature.

[0415] FIG. 17 exemplarily shows a method flowchart for restoring the factory settings provided by the present application.

[0416] S1711, receiving an operation of restoring the electronic device 100 to the factory settings.

[0417] Restoring the factory settings can be used to clear the data (for example, pictures, files, etc.) saved by the user, the information (for example, desktop wallpaper, mode flag bit of the AOD follow-up feature, etc.) set by the user, the non-system application programs downloaded by the user, and the like in the electronic device 100.

[0418] S1712, calling a formatting tool to clean up the data area of the electronic device 100, the data area including the mode flag bit of the AOD follow-up feature.

[0419] In response to the operation of restoring the electronic device 100 to the factory settings, the electronic device 100 can call a formatting tool to clean up the data area of the electronic device 100. Wherein, the electronic device 100 can restore the value of the mode flag bit of the AOD follow-up feature to the original value before the user sets.

[0420] For example, before the user sets the on-off state of the AOD follow-up feature, the value of the mode flag bit is empty. After the user turns on the AOD follow-up feature, the electronic device 100 can set the value of the mode flag bit to 1. In response to the operation of restoring the electronic device 100 to the factory settings, the electronic device 100 can delete the value "1" of the mode flag bit, so that the value of the mode flag bit returns to the empty state.

[0421] In some embodiments, the data area of the electronic device 100 can further include a parameter for controlling the movement of the AOD content. The parameter can refer to the description of step S1312 in the foregoing FIG. 13. The electronic device 100 can delete the parameter for controlling the movement of the AOD content from the memory by using the formatting tool.

[0422] In some embodiments, the electronic device 100 is communicatively connected with other devices having display screens. The electronic device 100 can use the display screen of the device connected therewith as an extended display screen. The electronic device 100 can be referred to as a master device. The device having the display screen as the extended display screen of the electronic device 100 can be referred to as a slave device. The data area of the slave device can store data of the communication connection between the slave device and the master device, a parameter for controlling the movement of the AOD content on the display screen of the slave device, and the like. The parameter for controlling the movement of the AOD content on the display screen of the slave device described above can be sent by the master device to the slave device.

[0423] When the master device (i.e., the electronic device 100) receives an operation of restoring the factory settings, the master device can send a data cleaning instruction to the slave device. The data cleaning instruction can be used to instruct the slave device to clear the data of the communication connection between the slave device and the master device, the parameter for controlling the movement of the AOD content on the display screen of the slave device, and the like.

[0424] FIG. 18 exemplarily shows a software structure diagram of the electronic device 100.

[0425] As shown in FIG. 18, the electronic device 100 can include a folding state acquisition module, an AOD motion effect adjustment module, an AOD resource management module, and a notification module.

[0426] The folding state acquisition module can be used to determine the folding state of the folding screen of the electronic device 100. For example, the folding screen of the electronic device 100 is the three-fold screen shown in the foregoing FIGS. 2A and 2B. The folding state of the folding screen can include the nine folding states shown in the foregoing FIGS. 2A and 2B. In some embodiments, the folding state acquisition module can acquire the folding angle between two adjacent display screens in the folding screen, and then determine the folding state of the folding screen according to the folding angle. The method of determining the folding state can refer to the description in step S912 shown in the foregoing FIG. 9.

[0427] The AOD motion effect adjustment module can be used to move the AOD content on the display screen according to the current folding state of the folding screen, the gaze area of the user on the screen, the touch operation of the user on the screen, and the like. In the process of moving the AOD content, the AOD motion effect adjustment module can further display the animation of the movement of the AOD content. The scene and method of moving the AOD content by the AOD motion effect adjustment module can refer to the description of the foregoing embodiments.

[0428] The AOD resource management module can be configured to manage AOD resources. The AOD resources can be pre-installed in the electronic device 100 or downloaded by the electronic device 100. The AOD resource management module can provide the user with options corresponding to the AOD resources for the user to select the AOD resource to be used. The AOD resource management module can send the AOD resource selected by the user to the AOD effect adjustment module, so that the AOD effect adjustment module displays the AOD content in the AOD resource selected by the user in the screen-off display state.

[0429] The notification module can be configured to obtain an event for triggering movement of the AOD content and notify the AOD effect adjustment module. In this way, the AOD effect adjustment module can move the AOD content according to the event for triggering movement of the AOD content.

[0430] The electronic device 100 can include more or fewer modules than those shown in FIG. 18, or combine some modules, or split some modules, without being limited to the modules shown in FIG. 18.

[0431] FIG. 19 illustrates a flowchart of a screen-off display method according to an embodiment of the disclosure.

[0432] S1911, the first device detects a screen-off event, the first device including a first display area and a second display area.

[0433] The first device can be the electronic device 100 in the foregoing embodiments. The screen-off event can refer to the description of step S911 in FIG. 9 or step S1611 in FIG. 16. The first display area and the second display area are at least partially different. The first display area can refer to the display area a1 in step S912 in FIG. 9. The second display area can refer to the display area a2 in step S913 in FIG. 9 or the display area a3 in step S914.

[0434] S1912, according to the screen-off event, the first device displays AOD content in the first display area, and when the first display area displays the AOD content, the second display area is in a powered-off state.

[0435] In some embodiments, the first display area described above can be a display area that displays AOD for the first time after the first device is powered off.

[0436] In some embodiments, the first device is a foldable screen device. The first device can determine the first display area according to the folding state of the foldable screen, which can refer to the description of step S912 in FIG. 9.

[0437] In some embodiments, before detecting the screen-off event, both the first display area and the second display area are in the powered-on state. In response to the screen-off event, the first device can keep the first display area in the powered-on state, display the AOD content on the first display area, and power off the second display area. Alternatively, in response to the screen-off event, the first device can first power off the first display area and the second display area, then power on the first display area, and display the AOD content on the first display area.

[0438] Optionally, in addition to the first display area and the second display area, the first device can further include other display areas. In response to the screen-off event, the first device can power off the display areas in the powered-on state except the first display area, and keep the display areas in the powered-off state except the first display area in the powered-off state. That is, when the first display area displays the AOD content, the display areas except the first display area can be in the powered-off state.

[0439] S1913, the first device detects a first event.

[0440] The first event can include but is not limited to: the human eye gazes at the second display area, or the user performs a touch operation on the second display area. The method for the first device to detect the human eye gaze area can refer to the description of step S913 shown in the foregoing FIG. 9. The method for the first device to detect the touch operation of the user on the display area can refer to the description of step S914 shown in the foregoing FIG. 9. Here, no longer be described in detail.

[0441] S1914, according to the first event, the first device powers on the second display area, displays the AOD content on the second display area, and keeps the first display area in the powered-off state when the second display area displays the AOD content.

[0442] In some embodiments, according to the first event, the first device can power off the display areas (for example, the first display area) in the powered-on state except the second display area, and power on the second display area to display the AOD content on the second display area. In this way, the display area of the AOD content can be switched from the first display area to the second display area.

[0443] In some embodiments, before displaying the AOD content on the second display area, the first device can play a first animation corresponding to moving the AOD content from the first display area to the second display area. For example, the first animation can include a first image sequence. The images in the first image sequence can be arranged in order of display. Among them, the earlier the image in the first image sequence is arranged, the more part of the image is displayed on the first display area. The later the image in the first image sequence is arranged, the more part of the image is displayed on the second display area. In this way, the display position of the image in the first image sequence can gradually move from the first display area to the second display area according to a preset moving path. The image content of the multiple images included in the first image sequence can be different (for example, the first image sequence includes multiple images of butterflies flying, and the state of the butterflies flying in each image is different). In this way, the animation effect of the object in the AOD content moving dynamically from the first display area to the second display area can be presented. Alternatively, the image content of the multiple images included in the first image sequence can be the same. That is, the AOD content can be a static image, and the first device can translate the static image from the first display area to the second display area.

[0444] The scenario in which the first device plays the first animation can refer to the scenario shown in the foregoing FIG. 4A-FIG. 4E, or the scenario shown in the foregoing FIG. 5A-FIG. 5C, or the scenario shown in the foregoing FIG. 6A-FIG. 6E, or the scenario shown in the foregoing FIG. 7A-FIG. 7C, or the scenario shown in the foregoing FIG. 8A-FIG. 8E.

[0445] In some embodiments, the first device further includes a third display area. The third display area can be a display area through which the AOD content moves from the first display area to the second display area. According to the first event, the first device can power on the second display area and the third display area. The first device can move the AOD content from the first display area to the third display area, and then move the AOD content from the third display area to the second display area. Then, the first device can power off the first display area and the third display area.

[0446] Among them, when the AOD content moves to the first position of the first display area, the first device can power on the third display area. The distance between the boundary of the first display area and the third display area and the first position is less than the first threshold. That is to say, when the AOD content is about to move from the first display area to the third display area, the first device can power on the third display area.

[0447] When the AOD content moves to a second position of the third display area, the first device can power on the second display area. A distance between a boundary of the third display area and the second display area and the second position is less than the second threshold. That is, when the AOD content is about to move from the third display area to the second display area, the first device can power on the second display area.

[0448] When the AOD content moves out of the first display area completely, the first device can power off the first display area. When the AOD content moves out of the third display area completely, the first device can power off the third display area.

[0449] It can be seen that the first device can power on the third display area and the second display area at different times. The first device can also power off the first display area and the third display area at different times. The above embodiments can better reduce the power consumption of the first device in the screen-off display state.

[0450] The above scenario in which the AOD content moves from the first display area to the second display area through the third display area can refer to the scenario in which the AOD content moves from the A screen to the C screen through the B screen as shown in FIGS. 4C-4E.

[0451] In some embodiments, during the movement of the AOD content from the first display area to the second display area, the first device can play a first audio.

[0452] In some embodiments, the first device can be a foldable screen device. The first device can further include a fifth display area. When the first device is in a first folding state, the AOD content can be displayed on the second display area. When the folding state of the foldable screen of the first device changes from the first folding state to a second folding state, the first device can display the AOD content on the fifth display area. The first folding state and the second folding state can be different. The first folding state and the second folding state can each be one of a fully unfolded state, a half-folded state 1, a half-folded state 2, and a fully folded state.

[0453] The fifth display area can be a preset area that is used to display the AOD content for the first time after the folding state of the foldable screen changes to the second folding state.

[0454] Optionally, during the change of the folding state of the foldable screen from the first folding state to the second folding state, the first device can play a second animation corresponding to the movement of the AOD content from the second display area to the fifth display area. The scenario in which the first device plays the second animation can refer to the scenario shown in FIGS. 11A-11C.

[0455] It can be seen that the first device can move the AOD content as the folding state of the foldable screen changes.

[0456] In some embodiments, the first device is connected with the second device. The screen of the second device can be an extended display screen of the first device. When the AOD content is located in the second display area, the first device detects a third event. The third event can include that a human eye gazes at the screen of the second device, or a user performs a touch operation on the screen of the second device. According to the third event, the first device can instruct the second device to power on the screen of the second device, and display the AOD content on the screen of the second device. When the screen of the second device displays the AOD content, the screen of the first device can be in a powered-off state. That is, the first display area and the second display area are in the powered-off state.

[0457] Optionally, the screen of the second device supports partition power-on and power-off. The AOD content can be displayed in a partial area of the screen of the second device. The first device can instruct the second device to power on the partial area of the screen of the second device for displaying the AOD content. When the partial area of the screen of the second device displays the AOD content, the area of the screen of the second device that does not display the AOD content can be in a powered-off state.

[0458] As can be known from the method shown in FIG. 19, in the screen-off display state, the first device can move the AOD content between the multiple display areas of the display screen according to the change of the gaze direction of the human eye or the change of the touch area. In this way, the interactivity of the AOD content can be improved. Moreover, the first device can power on the display area that displays the AOD content, and power off the display area that does not display the AOD content. This not only can reduce the power consumption of the first device in the screen-off display state, and realize all-day display of the AOD content on the display screen, but also can reduce the damage of the display screen caused by the long-time power-on state of the display screen. The above method can improve the user experience of the user using the AOD.
